Question

What is the valancy of nitrate?

Answer 1

 the valancy of nitrate is -1

Answer 2

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]
