Question

Quizplus · Accepted Answer

The identity of an element is determined by the number of protons in its nucleus. Changing the number of electrons alters the ionization state but not the element itself. Changing the number of neutrons changes the isotope of the element but not the element. Therefore, both electrons and neutrons can be changed without affecting the element identity.
