→O

In NO3− ion, Due to the presence of one negative charge, number of valence electrons =5+1=6.
One O-atom forms two bonds (= bond) and two O-atom are shared with two electrons of N atom Thus, 30 -atoms are shared with 8 electrons of N -atom.
Number of bond pairs (or shared pairs) =4 Number of lone pairs =0
