Can the atomic mass of an element change?

Question

Quizplus · Accepted Answer

The atomic mass of an element can change if there is a change in the number of neutrons, which is the basis for isotopes. Isotopes are atoms of the same element with different numbers of neutrons, resulting in different atomic masses but not forming a different element. Adding or losing electrons or protons can change the ionization state of an atom, but it does not change the atomic mass or result in a different element.
