Phosphate is H3PO4 and phosphite is H3PO3. Phosphoric acid, when neutralized with a base, such as ammonium or potassium, forms a salt (Phosphate). Phosphorous acid also forms a salt when neutralized with a base (Phosphite). Thus, Phosphite has one less oxygen molecule than Phosphate.
Also phosphorous is the ion (PO3)3-.
There are 18 electrons in a chloride ion.
The ion Fr+ has 86 electrons.
a cuprous ion has 28 electrons.
Phosphorous has 5 valence electrons. So, you need 3 more to complete it.
