Answer 2

Answer:

Polyatomic radicals : These are the chemically charged species made up more than one atoms acting as a single unit. All the atoms are covalently bonded to each other due to which these species act as a single unit.

For example:

• Ammonium ion is composed of one nitrogen and four hydrogen atoms with charge of '+1',$NH_4^+$.
• Sulfate  ion is composed of one sulfur and four oxygen atoms with charge of '-2',$SO_4^{2-}$.
• Phosphate ion is composed of one phosphorus and four oxygen atoms with charge of '-3,$PO_4^{3-}$.
