Question

Name the polyatomic ion that carries a positive charge.

Answer 1

• An ion is formed when an atom losses or gains electrons.
• Ions are made up of one or more kinds of atoms.
• An ion that consists of a group of atoms with an overall charge is called a polyatomic ion.
• An example of a polyatomic ion having a negative charge is a carbonate ion ${\mathrm{CO}}_3^{2-}$ and a positive charge is an ammonium ion $\left({\mathrm{NH}}_4^{+}\right)$.

Hence, the polyatomic ion that carries a positive charge is the ammonium ion $\left({\mathrm{NH}}_4^{+}\right)$.
