Question

which phrase describes transmutation? (1 point) the conversion of an atom of one element into a different element through nuclear changes the conversion of energy to matter through chemical changes the conversion of one substance to another through chemical changes the conversion of protons to neutrons through nuclear changes

Explanation:

Transmutation refers to the conversion of an atom of one element into a different element through nuclear changes. Chemical changes only involve the rearrangement of electrons and not a change in the element itself. Conversion of protons to neutrons is a part - process within nuclear reactions related to transmutation but is more specific. Conversion of one substance to another through chemical changes is a regular chemical reaction, not transmutation. Conversion of energy to matter through chemical changes is not possible as chemical changes do not involve conversion of energy to matter at that scale; nuclear reactions are associated with energy - matter conversion.

Answer:

the conversion of an atom of one element into a different element through nuclear changes
