(iv) NO
(iii) NO2
(h) Magnesium in Mg2N2​

Answer 1

Answer:

1. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.
2. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.
3. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.(c) Phosphorous is +3.
4. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.(c) Phosphorous is +3.(d) Carbon is +6.
5. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.(c) Phosphorous is +3.(d) Carbon is +6.(e) Valency of N:
6. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.(c) Phosphorous is +3.(d) Carbon is +6.(e) Valency of N: (i) N2O3 - Valency = +3
7. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.(c) Phosphorous is +3.(d) Carbon is +6.(e) Valency of N: (i) N2O3 - Valency = +3 (ii) N2O5 - Valency = +5
8. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.(c) Phosphorous is +3.(d) Carbon is +6.(e) Valency of N: (i) N2O3 - Valency = +3 (ii) N2O5 - Valency = +5 (iii) NO2 - Valency = +4
9. (a) Valency of Fluorine is -1, since valence electron is 7, so 7-8= -1.(b) Sulphur is +6.(c) Phosphorous is +3.(d) Carbon is +6.(e) Valency of N: (i) N2O3 - Valency = +3 (ii) N2O5 - Valency = +5 (iii) NO2 - Valency = +4 (iv) NO - Valency = +2
