Hidden G Posted May 26, 2011 Report Share Posted May 26, 2011 hello,i need an answer here,not exactly hints, is aluminum corrosion covalent or ionic? i'm getting two different solutions. and it's being proved that this bond is ionic but with covalent description. because AL is in the III group and O is in the VI , so they are both non-metal so covalent,isn't it? or i'm missing something?

0 benjer3 Posted May 27, 2011 Report Share Posted May 27, 2011 Actually, aluminum is a metalloid-ish metal - it's right off of the zig-zag. But what really matters is the difference in electronegativity. For aluminum and oxygen, this is about 1.8. This puts the bond close to both ionic and covalent, as the change happens around electronegativity differences of about 1.8 to 2.2. So I'd say that goes along with what's being proven.
