1.	What are the numberof bond pairsand lone pairs of electrons on N - atom in NO_(3)^(-) ?
Answer» Solution :No. of valence electrons in N-atom ` = 5 + 1` (negative charge ) = 6 One O-atom FORMS a double BOND. Other two O-atoms shared with two electrons of N-atom. ` :. ` No. of bond pairs = 4 No of LONE pairs = No. of valence electron - Bonding pairs ` = 4 - 4 = 0 ` ` :. ` No. of lone pairs = 0
