Phosphorus forms many oxoacids. Log in. (iv) Ionization enthalpy: Ionization enthalpy decreases down the group due to gradual increase in atomic size. Since H3PO2 has an overall neutral (zero) charge, and H has a charge of 1+, 3 times 1 = 3+ O has a charge of 2- by default, so, since there are 2 Oxygen atoms, 2 times -2 = an overall charge of -4 for Oxygen. Of phosphorus in H3PO2 molecule. Phosphorus forms many oxoacids. - 19273515 CAS Number. It's all to do with the oxidation state of the phosphorus and "hypo" in the name has nothing to do with hydrogen.
