To understand this question, we need some knowledge on radioactive decay. This type of nuclear decay is called a beta decay
<h3>Beta Decay</h3>This is the process where a radioactive material is fired or naturally emits a beta particle which is equivalent to the lose of an electron and spontaneously becomes an entirely different element.
The participating actors in this nuclear reaction are
- helium
- lithium
- electron
This is the decay process of helium particle in which it became a lithium particle and emitted an electron in the process.
