Question

Why do atoms decay? explain if possible it can be simple

Answer 1

Atoms radioactively decay when a lower-energy nuclear configuration exists to which they can transition.

Step-by-step explanation:

The actual decay event of an individual atom happens randomly and is not the result of the atom getting old or changing through time.

Answer 2

Step-by-step explanation:

In a nutshell, atoms decay because they're unstable and radioactive. Ununoctium (or Oganesson) has an atomic number of 118. That means that there are 118 protons in the nucleus of one atom of Oganesson, and that isn't including the number of neutrons in the nucleus.
