Explanation:

In a period , as we go from left to right in a periodic table, atomic number increases .

Differentiating electrons enters into same shell hence the effective nuclear charge decreases .

Hence atomic radius decreases along period.

Conculsion:

Aluminium is the element which has greater atomic radius and sulphur has smaller atomic radius.
