Answer: The correct answer is Group 3A, Period 3

Explanation:

Atomic number of aluminium is 13. As here n = 3 this means that aluminium element belongs to period.

Since, it contains 3 unpaired electrons. Therefore, in order to attain stability it will readily lose its valence electrons and hence, acquires as charge of +3.

This means that aluminium element belongs to group 3A and period 3. As it is a p-block element.

Thus, we can conclude that aluminium is located in Group 3A, Period 3.
