Why do we crossover the valencies of combining atoms in chemical formulas?

  • 1

Crossover ensures that the total positive charge from cations balances the total negative charge from anions, resulting in a neutral compound according to the law of electrical neutrality.

  1. We cross over valencies in chemical formulas to balance charges and create electrically neutral compounds. By swapping valencies between atoms, we ensure that the total positive and negative charges cancel out, forming a stable compound.
