What is the Valency Of Nitrate ?
Dear Mysha,
Nitrate ion (NO3) has one Nitrogen and three Oxygen atoms.
Oxygen lies in group 16 and thus has a valency of -2.
Nitrogen lies in the group 15 and has a charge of +5 forming the bond with three oxygen atoms.
N= 5
O= -2
NO3= 5+ 3(-2)
5-6=-1
The valency of Nitrate is -1.
