Question

A group of atoms of different elements functioning together as a single unit and carrying a charge -----------------------

Answer 1

Radical or Ion: A group of atoms of different elements functioning together as a single unit and carrying a charge (positive or negative) is known as a radical.

• A radical is not capable of independent existence.
• It always combines with another radical or element.

Example: Positive radicals : .${\mathrm{Na}}^{+},{{\mathrm{NH}}_4}^{+}\mathrm{etc}...$.

Negative radical : .${\mathrm{F}}^{-},{\mathrm{O}}^{-2},{{\mathrm{CO}}_3}^{-2}\mathrm{etc}..$

Therefore a group of atoms of different elements functioning together as a single unit and carrying a charge Radical or Ion
