(Nitrogen and Sulphur both have variable valencies) S of SO3 (H2SO3) has +4 valency and S of SO4 (H2SO4) have +6 valency. In other words, valency of nitrate ion is -1. Absorption of solar radiation in this region leads to photodissociation and thus a very short atmospheric lifetime during the day. The valency of carbonate is two because it can combine with two hydrogen atoms. Balance the equation. R. P. Wayne, I. Barnes, P. Biggs, J. P. Burrows, C. E. Canosa-Mas, J. Hjorth, G. Le Bras. Lv 7.

Hope it helps!!! # electrons in one-third of a π bond = 2/3. Valency of (-NO3) is (-1), because last electronic configuration of N is 2s2 2p3 means outer orbit contains 5e- where as oxygen contains 6e- in last orbit but oxygen has more electronegative hence electron pull by oxygen. Simply applying this logic, Nitrogen in NO3-1 has -2*3 = -6 -1 = +5 valency. The formulae of acids and of more covalent molecules is not easy to … Sulphur has 6 electrons in its outer shell. For the Lewis structure for NO3- you should take formal charges into account to find the best Lewis structure for the molecule. 0 10. CO3 2- is carbonate.
