Lewis Structures Charges Always Balanced?

Postby Hector_Gutierrez 1J » Mon Oct 24, 2016 10:16 pm

Is the ideal Lewis Structure always balanced? To be more specific, will the formal charge on every atom in a molecule always be zero? Or will the most ideal state of a molecule sometimes have atoms with positive or negative formal charges?

If your definition of "ideal" is stability, then yes. Molecules always try to have Lewis structures that are most stable in which the formal charges are as close to zero as possible. Take into account that the sum of formal charges should still add up to the charge of the ionic molecule itself.
