5p

Explanation:

When the 4d is filled the electrons fall down into the fourth energy level leaving only the 5th shell to be filled

The 5s and 4d fill up concurrently. Sometimes the 5s being filled first and sometimes the 4d being filled first. When the 4d is filled the 5s is also filled. This leaves the 5p to be filled next.
