Element X is a 5^(th) period Transition element.

Explanation:

Since, 5s orbital is fully filled, so the element X lies in 5^(th) principal shell, i.e. it lies in the 5^(th) period.

Now, since the 4d subshell is partially filled, so it is certain that the element X is a 5^(th)period transition element.
