Question

Explain how chloride ion is formed?

Answer 1

Formation of chloride ion:

1. A chloride ion is a negatively charged ion i.e. anion, which has one unit of negative charge.
2. A chlorine atom $\left(\mathrm{Cl}\right)$ gains one electron in the outermost shell and forms a chloride ion $\left({\mathrm{Cl}}^{-}\right)$.
3. The reaction is as follows: $\mathrm{Cl}+{\mathrm{e}}^{-}\to {\mathrm{Cl}}^{-}$

Thus, a chloride ion is formed when a chloride atom gains one electron.
