Answer:
1. Aluminium (Al) {2,8,3}
No. of shells = 3 (K,L,M)
No. of electrons in valence shell = 3
Valency = 3
2. Chlorine (Cl) {2,8,7}
No. of shells = 3 (K,L,M)
No. of electrons in valence shell = 7
Valency = (8-7) = 1
3. Calcium (Ca) {2,8,8,2}
No. of shells = 4 (K,L,M,N)
No. of electrons in valence shell = 2
Valency = 2
