Question

Why does radioactive decay occur? ?

Answer 1

because some atoms are too big and this makes them unstable. Through radioactive decay they become a smaller atom and become more stable.

Answer 2

Step-by-step explanation:

A radioactive decay is the spontaneous emission of radionuclides through which an unstable parent atomic nucleus breaks into simpler and more stable daughter nuclei.

Radioactive decay occurs when the nucleus of an atom is unstable; when there is imbalance between the number of protons and neutrons present in the nucleus. All atoms want to be stable, the absence of this stability in the nucleus causes radioactive decay. Electrons are not involved in radioactive decay because this decay occurs in the nucleus and electrons are not found in the nucleus.
