WebZinc exhibits only the +2 oxidation state. It can give up two electrons to form an electrovalent compound; e.g., zinc carbonate ZnCO 3. It may also share those electrons, as in zinc chloride, ZnCl 2, a compound in which the bonds are partly ionic and partly covalent. Dipositive mercury also forms covalent bonds in mercuric chloride, HgCl 2. Web(remember Al is sometimes considered both metal and non-metal ~ you know, a metalloid) You can also think of it like this, Al would have to lose 3 v.e- to achieve an octet(or Ne Electronic config.)=13 proton holding onto just 8 v.e-, and Al is quite a small atom, therefore it will have a moderate electronegativity (not too less like in metals),
