Question

what is the valency of Nitrogen in NO2 and Nitrogen in NO...with explanation pls​

Answer 1

Answer:

here is your answer

Explanation:

Valency of Oxygen is always -2.

So in these compounds valency of Nitrogen can be calculated by following ways.

1.

In N2O:

Let X is the valency of Nitrogen N So

2*X+(-2)=0

2X=2

X=1

In N2O valency of Nitrogen is +1.

2.

In NO2:

As oxygen valency is always -2.

Let X is the valency of Nitrogen N So

X+2*(-2)=0

X-4=0

X=4

In NO2 valency of Nitrogen is +4.

Answer 2

Answer:NO2-4+

NO-2+

Explanation:

We know an atom is neither positive nor negative,therefore NO2 and NO are also neutral.

We know oxygen has a valency of 2-.

case 1:

let valency of n be x+

x+ + 2 molecules of oxygen*2- =0

x+ + 4- =0

hence x =4
