what type of isotope undergoes radioactive decay?\none that has a nucleus with the same number of protons and neutrons\none that has an unstable nucleus\none that has the same number of protons and electrons\none that has a stable nucleus

Answer

Brief Explanations:

Radioactive decay occurs in isotopes with unstable nuclei as they try to reach a more stable state. Isotopes with stable nuclei do not undergo radioactive decay. Having equal numbers of protons and neutrons or protons and electrons does not directly determine if decay will occur.

Answer:

one that has an unstable nucleus
