“Atoms cannot be created.”
The conclusion
Nuclear processes demonstrably create new atoms from existing particles. Stellar nucleosynthesis, fusion, fission, and laboratory bombardment produce nuclei of new atoms; conservation laws governing matter, energy, or baryon number do not prohibit such formation. The statement would require an unstated “from nothing” qualification to be defensible.
Caveats
- The claim equivocates between forming atoms and creating matter from nothing.
- Baryon-number conservation does not imply conservation of atomic number, identity, or count.
- In ordinary chemical reactions, atoms are generally rearranged rather than newly produced, but the claim is not limited to chemistry.

Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons. … Stars can create nuclei through two processes: either by combining two smaller nuclei (called fusion) or breaking a larger nucleus into multiple nuclei (called fission). Both ways result in new atoms.
The alchemy, or the transformation of atomic nuclei, that gives rise to the elements arises in nuclear reactions, which only occur in nature under the most extreme conditions. … The Big Bang created the lightest elements
Stellar nucleosynthesis is defined as the process by which elements are formed through nuclear reactions in stars … Within galaxies, stars and supernovae play the dominant role both in synthesizing the elements from carbon to uranium … In the first few minutes of its history, our universe processes about one fourth of its baryonic material into helium-4 during an epoch known as Big Bang Nucleosynthesis(BBN).
Baryon number conservation is not guaranteed by any fundamental symmetry within the standard model, and therefore has been a subject of experimental and theoretical scrutiny for decades. So far, no evidence for baryon number violation has been observed.
As long as energies below the Ineson pmduction threshoM are not exceeded, all "prompt" nuclear processes can be described as the shufHing and reshuRhng of protons and neutrons into the variety of nucleonic packs called nuclei. … Only at very high energies can nucleons be produced or annihilated.
Nuclear fission is the process where the nucleus of an atom splits into two or more smaller nuclei and other particles.
Physicists create baryonic matter all the time by smashing subatomic particles together with all the power their equipment can muster.
B and L quantum numbers are not imposed by any fundamental symmetry or principle in SM. Instead, B and L emerge as accidental global symmetries of the renormalizable Lagrangian [20]. In particular, given the SM field content and gauge invariance there are no Lorentz and gauge invariant operators of dimension d ≤ 4 that violate either B or L. All renormalizable interactions are found to automatically conserve these quantum numbers.
The chemical elements that make up the matter we observe throughout the universe were created in these reactions. … It took hundreds of thousands of years of further cooling until the average energies of nuclei and electrons were low enough to form stable hydrogen and helium atoms.
In nuclear fusion, atoms are combined, or fused, together to form a larger atom.
"Nucleosynthesis" will be used hereafter, without political implications, to mean the building up of heavy elements from lighter ones (and occasionally back again).
The process of producing new elements is called nucleosynthesis. … Stars are responsible for the nucleosynthesis beyond helium
Every atom of carbon, oxygen, nitrogen, calcium, and iron in the universe was synthesized inside a star through specific nuclear reactions whose rates are determined by the nuclear physics we have developed in this textbook.
A balanced chemical reaction equation reflects the fact that during a chemical reaction, bonds break and form, and atoms are rearranged, but the total numbers of atoms of each element are conserved and do not change. … The first element to be prepared that does not occur naturally on the earth, technetium, was created by bombardment of molybdenum by deuterons
By solving the equations numerically, we show “electron-positron oscillations”, the fluctuations originated from virtual electron-positron pair creations and annihilations, appear in the charge density of a hydrogen atom and molecule.
For the maintenance of a self-sustaining chain reaction, however, it is not necessary that every neutron produced in fission initiate another fission. The minimum condition is for each nucleus undergoing fission to produce, on the average, at least one neutron that causes fission of another nucleus.
The law implies that mass can neither be created nor destroyed, although it may be rearranged in space, or the entities associated with it may be changed in form. … In special relativity, the conservation of mass does not apply if the system is open and energy escapes. However, it does continue to apply to totally closed (isolated) systems.
In contrast, for a typical nuclear reaction, such as the radioactive decay of 14C to 14N and an electron (a β particle), there is a much larger change in mass: … The reaction involves the conversion of a neutral 14C atom to a positively charged 14N ion (with six, not seven, electrons) and a negatively charged β particle (an electron), so the mass of the products is identical to the mass of a neutral 14N atom.
In general, the atomic number is not conserved in nuclear reactions.
A balanced chemical reaction equation reflects the fact that during a chemical reaction, bonds break and form, and atoms are rearranged, but the total numbers of atoms of each element are conserved and do not change. … A balanced nuclear reaction equation indicates that there is a rearrangement during a nuclear reaction, but of nucleons (subatomic particles within the atoms’ nuclei) rather than atoms.
Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
A balanced chemical reaction equation reflects the fact that during a chemical reaction, bonds break and form, and atoms are rearranged, but the total numbers of atoms of each element are conserved and do not change. … The first nuclide to be prepared by artificial means was an isotope of oxygen, 17 O. It was made by Ernest Rutherford in 1919 by bombarding nitrogen atoms with α particles:
The mission of the Nuclear Physics (NP) program is to explore the nature of matter: its basic constituents and how they interact to form the elements and the properties we observe.
Unlike nuclear processes, chemical reactions do not create or destroy atoms, or change one kind of atom into another.
The law of conservation of baryon number was proposed in 1938 by Ernst Stueckelberg. Baryon number is a 'conserved' quantity in the sense that for perturbutative reactions in the Standard Model the total baryon number of the incoming particles is equal to the baryon number of the outgoing particles.
In nuclear physics and nuclear chemistry, a nuclear reaction is a process in which two nuclei, or a nucleus and an external subatomic particle, collide to produce one or more new nuclides. Thus, a nuclear reaction must cause a transformation of at least one nuclide to another.
Fusion reactions. Occur when two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus.

The idea of mass conservation plus a surmise that certain "elemental substances" also could not be transformed into others by chemical reactions, in turn led to an understanding of chemical elements, as well as the idea that all chemical processes and transformations (such as burning and metabolic reactions) are reactions between invariant amounts or weights of these chemical elements.
A straightforward interpretion for the operators \(\hat{\psi}^\dagger(\mathbf{r})\) and \(\hat{\psi}(\mathbf{r})\) is that they respectively create and annihilate one particle at a point \(\mathbf{r}\) (rather than one particle in a given eigenstate).

Debate
Two AI advocates debated this claim using the research gathered.
Argument for
The overwhelming weight of authoritative, verified sources — DOE (Source 1, Source 6), the Royal Society (Source 2), ScienceDirect (Source 3), and the classic Burbidge et al. paper (Source 5) — consistently describe nucleosynthesis and nuclear reactions not as creation of atoms from nothing but as the 'shuffling and reshuffling' of pre-existing protons and neutrons into new configurations, meaning every 'new' atom is merely a rearrangement of already-existing nucleons, exactly as baryon number conservation (Source 4, Source 8, Source 26) and mass-energy conservation in closed systems (Source 18) require. Even Scientific American's note on particle colliders 'creating' baryonic matter (Source 7) refers to converting energy into fundamental particles via E=mc², not the spontaneous creation of atoms from nothing, so across cosmology, nuclear physics, and particle physics the consensus is unambiguous: atoms and their constituent baryons are transformed and conserved, never truly created from nothing.
The Proponent commits a strawman fallacy by conflating the conservation of fundamental baryons (Source 4, Source 8) with the conservation of atoms, falsely implying that assembling pre-existing components does not constitute creation. By arbitrarily requiring creation to mean generation ex nihilo, the Proponent ignores the Department of Energy's explicit definition that nucleosynthesis directly results in the "creation of new atomic nuclei" and "new atoms" (Source 1).
Argument against
The claim that atoms cannot be created is demonstrably false, as natural processes like stellar nucleosynthesis continuously form new atoms through nuclear fusion and fission (Source 1, Source 3). Furthermore, scientists routinely create entirely new atoms artificially in laboratories, such as the synthesis of technetium via particle bombardment, proving that atomic creation is a fundamental and observable physical reality (Source 15).
The Opponent commits an equivocation fallacy by conflating 'creation' in the colloquial sense of forming a new configuration of nucleons with 'creation from nothing,' when Source 1 itself explicitly frames nucleosynthesis as fusion or fission of pre-existing nuclei, and Source 15's technetium example is merely bombardment rearranging existing protons and neutrons from molybdenum, not conjuring atoms ex nihilo. This selective reading ignores Source 5's explicit characterization of these processes as the 'shuffling and reshuffling' of protons and neutrons and Source 4/Source 8's demonstration that baryon number is conserved, which together confirm no atom is created without pre-existing nucleonic matter as its source.
Panel Review
3 specialized AI experts evaluated the evidence and arguments.
Reviewer 1 — The Logic Examiner
Sources 1, 3, and 15 directly establish that nuclear reactions and laboratory bombardment form new atomic nuclei/atoms from prior particles, which is a counterexample to the categorical claim; conservation of baryon number in Sources 4 and 8 does not entail conservation of the number or identity of atoms. The proponent's ex-nihilo reinterpretation adds a condition absent from the claim, while the opponent correctly distinguishes constituent conservation from atom creation, so the claim is false under its stated wording.
Reviewer 2 — The Source Auditor
High-quality sources, including energy.gov (Source 1) and sciencedirect.com (Source 3), explicitly state that new atoms are created through processes like nucleosynthesis, fusion, and fission. While fundamental particles like baryons are conserved, the atoms themselves are formed and created from these constituents, rendering the claim that atoms cannot be created false.
Reviewer 3 — The Precision Analyst
The claim 'atoms cannot be created' is a bare, unqualified assertion with no scope or definitional qualifier, yet the evidence pool overwhelmingly shows that new atoms ARE routinely created in the ordinary sense of the word: Source 1 explicitly calls nucleosynthesis 'the creation of new atomic nuclei' and states fusion/fission 'result in new atoms,' Source 15 and Source 23 describe technetium and oxygen-17 being artificially created via bombardment, and Source 10/Source 29 describe fusion as combining atoms into new ones. The Proponent's rebuttal that this is merely 'rearrangement of nucleons, not creation from nothing' imports an unstated ex-nihilo qualifier that is absent from the claim as worded; as phrased, the claim overstates conservation-of-baryon-number physics into a flatly false statement about atoms, since atoms (as opposed to baryons/nucleons) are demonstrably created and destroyed in nuclear reactions.
Panel summary
Authoritative government and scientific sources consistently describe nucleosynthesis, fusion, fission, and particle bombardment as producing new nuclei and atoms. A single verified counterexample defeats the categorical assertion. Conservation of baryon number does not preserve the number or identity of atoms; existing particles can combine or transform into new atoms. The claim also lacks a qualifier limiting “created” to creation of matter from nothing. Under the ordinary scientific meaning of forming an atom, the evidence directly contradicts it.
