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 parentheses RULE 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.
