Question

Radioactive decay is likely to occur when ... radioactive decay is likely to occur when ... protons break into neutrons and electrons. atoms collide with one another. an electron hits the nucleus. an atom has too many neutrons. an atom has too many electrons.

Answer 1

Radioactivity or radioactive decay is the process that occurs when unstable isotopes or atoms release energy by emitting radiations such as ,gamma radiations, alpha radiations and beta radiations to attain stability. Therefore, in this case decay is likely to occur when a given atom has two many neutrons in its nucleus in order to attain stability.

Answer 2

Answer:

When an atoms has too many neutrons.

Explanation:

When an unstable atom loses energy and charged particles (radiation) through radiation it is a phenomenon called radioactive decay, when a substantial energy is lost the atom becomes stable.There are five types of radioactive decay:

1. Alpha decay
2. Beta negative decay
3. Gamma decay
4. Beta positive decay
5. Electron capture
