Answer:

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.
