Physical nature:- Ionic compounds are solids and are somewhat hard. Melting and Boiling points: - Ionic compounds have high melting and boiling points. Solubility: - Electrovalent compounds are generally soluble in water and insoluble in solvents such as kerosene, petrol, etc.

Conduction of Electricity: - Ionic compounds do not conduct electricity in the solid state but conduct electricity in the molten state or when dissolved in water. Most metals do not combine with hydrogen. Only a few reactive metals like sodium, potassium, calcium and magnesium react with hydrogen to form metal hydrides.
