What are polyatomic ions? Give examples?
Solution:\
A polyatomic ion is a group of atoms carrying a charge (positive or negative). For example, ammonium ion $\left(\mathrm{NH}_{4}^{+}\right)$, hydroxide ion $\left(\mathrm{OH}^{-}\right)$, carbonate ion $\left(\mathrm{CO}_{3}^{2-}\right)$, sulphate ion ( $\left.\mathrm{SO}_{4}^{2-}\right)$.
