Question

define ionic compound and give examples
class 10

Answer 1

Explanation:

Ionic compounds include salts, oxides, hydroxides, sulfides, and the majority of inorganic compounds. Ionic solids are held together by the electrostatic attraction between the positive and negative ions. For example, the sodium ions attract chloride ions and the chloride ion attracts sodium ions.

Answer 2

Ionic Compounds

What are Ionic Compounds ?

Ionic compounds are made of +vely charged cations and -vely charged anions.

Examples:

1. NaCl; made of  Na⁺ and Cl⁻
2. MgCl₂; made of Mg²⁺ and Cl⁻
3. AlCl₃; made of Al³⁺ and Cl⁻
4. NaOH; made of Na⁺ and OH⁻

More to know: Properties of Ionic Compounds:

1. The cations and anions have opposite charges. So, the forces of attraction between them are strong. Hence, they are solids at room temperature.
2. For the same reason, they conduct electricity only in aqueous or molten forms; not in solid state.
3. They are soluble in most organic solvents and insoluble in most inorganic solvents.
