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 protons to neutrons through nuclear changes the conversion of energy to matter through chemical changes the conversion of one substance to another through chemical changes

Explanation:

Transmutation is the process by which one element is changed into a different element via nuclear - level alterations. Proton - neutron conversion is part of nuclear reactions but not the full definition of transmutation. Energy - matter conversion through chemical changes is incorrect as transmutation is a nuclear process. Conversion of substances through normal chemical changes is a chemical reaction, not transmutation.

Answer:

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