2) NH₄NO₃

3) KCl

Answer:-

The cations in the given species are Ca²⁺, NH₄⁺, and K⁺.

The anions in the given species are O₂⁻, NO₃⁻, and Cl⁻.

• Ions are defined as charged species. They may be positively or negatively charged.
• The positively charged species are called cations while the negatively charged ions are called anions.
• Ionic compounds are formed by a cluster of these ions.  
• Some other examples of ions are Li⁺, Na⁺, Mg²⁺, Al³⁺, CO₃²⁻, I⁻,  etc
