Question

Which species Al or Cu will have the greater attraction for the chlorine atom?

Answer 1

Aluminium is an element in group three in the periodic table in period three while copper is a transition element. Aluminium is higher in the reactivity series than copper and therefore it is more reactive than copper. Aluminium has a valence of three and therefore will react with copper forming a strong ionic bond compared to copper which has a valency of 1 or two. Therefore aluminium has greater attraction for chlorine atom
