Formal charge on nitrogen and oxygen in N O 3 - ion are respectively: (a) 0, -1/3 (b) +1,-1/3 (c) +1,-2/3 (d) 0,-2/3
Dear student FC = V-N-B/2 where V = no of valence electron N = No. of non bonding electronsB = No. of electrons in covalent bondFormal charge of N on NO3- =0 Formal charge of O on NO3- = -1/3
Formula change is basically a change given to an atom, on assuming that the electrons in a chemical bond are shared equally between the atoms, neglecting theirrelative, EN.FC=V−N−2B (V=no. of valance electronN=No. of non bonding electronsB=No. of electrons in covalent bond)FC on N in NO3−=0FC on O in NO3−=3−1
