%���� We know that Br has a -1 charge and the are three bromide ions. If the compound is ionic, we use the principle of charge neutrality to name the compound.

Some of the metals form very common ions which have latin names that are in common use, and you need to be familiar with those in the following table.

If it is an acid, we base it's name on the ionic compound it would form if hydrogen could be a cation. WARNING: May cause irritation, skin or lung sensitization. Nitrogen forms different oxyanions than phosphorous or Arsenic, Oxygen does not form oxyanions, and although I have seen perfluorate, fluorate and fluorite salts on an exam and webpages where they form similar structures to chlorine, I believe the only one that really exists is hypofluorite (FlO-).
