Select all that apply Similarly, all species in Table \(\PageIndex{1}\) that lie above H2 are stronger reductants than H2, and those that lie below H2 are weaker. Aluminium(3+) is an aluminium cation that has a charge of +3. There must be a balance between the number of electrons lost and the number of electrons gained by atoms in the reaction. By applying the exactly same logic i can say L i X + is above A l X 3 + so it must have less ionic radius but that is not the case. Polyatomic ions with a positive 1 charge do occur, but the main one you'll encounter and need to know is the ammonium ion. C) dinitride trioxide.
