Answer 2

An ion is formed when an atom loses or gain electrons.

Explanation:

• When an atom loses or gains electrons it becomes an ion.
• The ions are basically of two types, these are cations and anions.
• Cations are positively charged ions that usually have more protons as compared to electrons. They have fewer electrons as these electrons are donated to some other atom.
• Anions are negatively charged ions that usually have more electrons as compared to protons. These anions have more electrons as these electrons are generally accepted from some other atoms.
• Therefore the answer is, an ion is formed when an atom loses or gain electrons.
