Chlorine has a smaller atomic size.
Explanation: As you move towards right of the periodic table, the atomic size decreases. This is because the number of protons is increasing towards the right of the periodic table, which applies a greater inward force on the electrons. that is why the elements on the right of the periodic table have a smaller atomic size when compared to the elements on the left. Since chlorine is on the right side of aluminium, it has a smaller atomic size.

aluminium has bigger atomic size than chlorine

because atomic radii decreases across the period and increases down the group

this law would hold owing to the fact that chlorine and aluminum are on the same period
