Determine the Formal Charge for oxygen 1 N: a) -2 b) +2 c) -1 d) O e) +1

Draw the Lewis structure of NCO (with minimized formal charges) and then choose the appropriate formal charges for each of the atoms. A) N = 0, C = 0, O = -1 B) N = -1, C = +1, O -1 + C) N = 0, C = 0, O = 0 D) N = +1, C = -1, O = -1 E) N = -1, C = 0, O = 0

In the Lewis structure for cyanate ion given below, what is the formal charge on the carbon atom?

Iodine forms a series of fluorides (listed here). Write Lewis structures for each of the four compounds and determine the formal charge of the iodine atom in each molecule:(a) IF(b) IF3(c) IF5(d) IF7
