Question

The valency of Nitrogen in the following is?

NO, NO2,N2O3

Open in App
Solution

valency of NO

Valency of Oxygen is 2 and Number of atoms in Oxygen is 2

x + 1*(-2) = 0
x=2
valency of NO =2


.



Let x be the valency of Nitrogen.NO2

Valency of Oxygen is 2 and Number of atoms in Oxygen is 2

x + 2*(-2) = 0

x = 4
valency of Nitrogen.NO2 =4

N2O3
Let x be the valency of Nitrogen.

Valency of Oxygen is 2 and Number of atoms in Oxygen is 2

2 x + 3*(-2) = 0

x = 6/2=3
valency of N2O3 is 3
