Mechanisms and rules for writing chemical formulas:

THE CRISS-CROSS METHOD

RULE 1: The resulting formula for a compound must have a total charge of zero (0). RULE 2: Write the positive ion first and cross the valences.RULE 3: Do not cross any signs.RULE 4: Don’t cross any ones.RULE 5: If both valences are the same, don’t cross them.RULE 6: More than one atom, more than one time, use parenthesesRULE 7: If the final answer has subscripts that can be reduced, they must be reduced. RULE 8: If the name of the compound has prefixes in it, change the prefixes to subscripts and do not cross the valences.
