The crisscross method is a way to determine the chemical formula of compounds by using the valence of the atoms. Atoms have a central core of protons and neutrons, with layers of electrons circling the core in layers called shells. The outermost shell may contain too many or few electrons, which is described by a plus or minus valence number.
