Select from the list below the correct formal charges for the atoms in the Lewis structure of NO3-(nitrate ion).
(a) 0 on all atoms
(b) -1 on doubly bonded O atom(s), 0 on singly bonded O atom(s), 0 on N.
(c) +1 on the N atom, -1 on singly bonded O atom(s), 0 on doubly bonded O atom(s).
(d) 0 on the N atom, -2 on singly bonded O atom(s), 1 on doubly bonded O atom(s).
(e) 0 on the N atom, 1 on singly bonded O atom(s), -1 on doubly bonded O atom(s).
Answer: +1 on the N atom, -1 on singly bonded O atom(s), 0 on doubly bonded O atom(s).
