Please help with Physical Science?

Radium-226 is unstable. what is the process that allows the nucleus of Radium-226 to become more stable?

A.) Hydrogen bonding

B.) Radioactive decay

C.) Ionic bonding

D.) Covalent bonding

E.) Nuclear fusion

Answer 1

`B.)`

Explanation:

Radioactive decay would be most suitable for radium-226 to be more stable.

Radium-226 has `88` protons, but `138` neutrons. Thus, it would want to decay, in order to get rid of some of the neutrons, and maybe transform into another element.

If an element has too many protons, but also too many neutrons, it would most likely undergo alpha-decay.

So, `B.)` is the correct answer.
