Answer

(a) Sodium Chloride :

Ionic equation

Na – 1e^– ⟶ Na¹⁺ [oxidation]
[atom] [cation]
[2,8,1] [2,8]

Cl + 1e^– ⟶ Cl^1- [reduction]
[atom] [anion]
[2,8,7] [2,8,8]

Na + Cl ⟶ Na¹⁺ Cl^1- ⟶ NaCl

(b) Calcium Oxide

Ionic Equation

Ca – 2e^– ⟶ Ca²⁺ [oxidation]
[atom] [cation]
[2,8,8,2] [2,8,8]

O + 2e^– ⟶ O^2- [reduction]
[atom] [anion]
[2,6] [2,8]

Ca + O ⟶ Ca²⁺O^2- ⟶ CaO
