Answer:
The gain of an electron.
Explanation:
<em>Ions are made when an atom does no longer have an equal number of protons and electrons.</em>
This would theoretically mean that in order for an atom to become an ion, it would have to either gain or lose an electron or a proton.
- However, protons are located in the nucleus, so the energy required to add or remove a proton is immensely higher than the energy required to add or remove an electron.
