Question

What is the valency of n in n2o3

Answer 1

Answer:

There are 3 oxygen atoms with 2 electrons required to achieve a stab le octet. The nitrogen atoms are two in numbers with 3 electrons required to stabilize the valence shell. In short, it can be said that the oxidation state of the nitrogen is 3.

Answer 2

Answer:

3

Explanation:

The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.
