1.what kind of charge for the ionic bond be between aluminum and 2oxygen [Aluminum valence electron 3 and oxygen is 6}.
Aluminum can give a electron away to each oxygen bet then where would the extra electron go and why and what kind of charge is that

The compound formed by reaction between aluminium and oxygen is aluminium oxide(Al2O3). So for the ionic bonding you have 2Al3+ ion and 3O2- ion.
The reason for this is because you have 2 atoms of aluminium and 3 atoms of oxygen. Also you can check whether you are right or not by adding the charges which always equals to zero in ionic compound.
for example for Al2O3 you have +6 for aluminium and -6 for oxygen which gives you zero if you add these charges.
Hope this helped.

There are more exotic combinations than Al2O3, like the neutral molecule AlO2, and the anion AlO2^-, which is sometimes called "aluminate" and has a -1 charge. The AlO3^3- anion is also called "aluminate".
There is no "giving" of electrons. The bonds in AlO2 or AlO2^- are covalent. In the AlO2^- anion there is an extra electron giving it the -1 charge. Aluminum is the central atom. There is a double bond to one oxygen and a single bond to the other oxygen.
