Question

What is Nitrate vallency and please answer immediately ​

Answer 1

NO3 (Nitrate ion) has three oxygen atoms and one nitrogen atom. Nitrogen belongs to group -15 in the periodic table and it forms bonds with three oxygen atoms with +5 charge. Oxygen belongs to the group – 16 in the periodic table, thus it has a valency f -2. So, the valency of nitrate ion is. 5 – [3 ✕ 2]. Which is (-1)

Answer 2

it's (-1)

Nitrate ion (NO3) has one Nitrogen and three Oxygen atoms. ... Nitrogen lies in the group 15 and has a charge of +5 forming the bond with three oxygen atoms. 5 – 3*(2) = -1. So if you add the valency of all the atoms, you get the answer as -1.

hope it helps✌︎
