In NO_(3)^(-)ion, the number of bond pairs and lone pa1rs of electrons

1.	In NO_(3)^(-)ion, the number of bond pairs and lone pa1rs of electrons on nitrogen atom are
Answer» 2,2 3,1 1,3 4,0 Solution :4,0 In N-atom, are = 5 valence electrons = 5 As the presence of one negative charge, NUMBER of valence electrons = 5 + 1 = 6 one O-atom forms TWO bond (= bond) and two O-atom shared with two electrons of N-atom So, 3 O-atoms shared with 8 electrons of N-atom. `therefore `Number of bond PAIRS (or shared pairs) = 4 Number of lone pairs = 0
