USE YOUR KNOWLEDE OF BONDING TO EXPLAIN?.aluminium combines readily with both dry flourine and dry chlorine.anyhydrous aluminium chloride is a white solid which sublimes at about 200 degres celcius ;it reacts with water and dissolves in non-polar solvents.alumiunium flouride is a crystalline solid up to tepreture in excess of 1290 degrees celcius ; it is insoluble in non polar solvents .
Aluminium is an electropositive element, its valence shell has 3 electrons known as 3s2 3p1 so it has tendancy to give its 3 electrons to an electronegative ele emts sich as fluorine and chlorine which have both 7 electrons on the valence shell and so aluminium can give 3 electrons to 3 atms of chlorine or fluorine to complete their valence shell
