Naming ionic formulae

When naming an ionic compound follow the the steps outlined below.

Step 1- identify the ions present in the compound.
Step 2 - place the positive ion first followed by the negative ion. If the ion has more than one charge, eg Fe2+ or Fe3+ indicate the charge by using brackets and Roman numerals. Iron(II) or Iron(III).
Step 3 - do not use di, tri or mono when naming the compound.
Example - What is the name of the compound with the following formula (NH4)3PO4

Step 1- identify the ions present . (The ions present are (NH4+) ammonium and (PO4-3) phosphate
Step 2 - place the positive ion first followed by the negative ion. Ammonium phosphate
Step 3 - do not use di, tri or mono when naming the compound. We do not write tri-ammonium phosphate to signify that three ammonium ions are present for each phosphate ion.
