What are the number of bond pairs and lone pairs of electrons of N-ato

1.	What are the number of bond pairs and lone pairs of electrons of N-atom in NO_(3)^(-) ?
Answer» Answer :No. ofvalence 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
