Which оf the fоllоwing stаtements concerning the formаl chаrge of an atom is/are true? 1. The formal charge of each individual atom in a molecule or ion is the actual atomic charge that can be determined experimentally. 2. The formal charge of each individual atom is always the same for each possible resonance form. 3. The sum of the formal charges of each atom in an ion equals the overall charge of the molecule or ion.
