PLEASE HELP

Answer 1

A) Ions...
Ions are atoms that have either lost or gained an electron.

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

When a neutral atom loses an electron then it acquires a positive charge.

For example, sodium on losing an electron become $Na^{+}$ ion.

On the other hand, if a neutral atom gains an electron then it acquires a negative charge.

For example, a neutral chlorine atom on gaining an electron forms $Cl^{-}$.  

Hence, an ion is formed in both the cases.

Thus, we can conclude that in the given situation these charged atoms called ions.
