Aluminum Element has Largest Atomic radius.

Explanation:
--------------------
Given Elements :
Aluminum, Silicon, Phophorous and Sulphur belongs to Third period.

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.
