Explanation:

The periodic table can be partitioned into blocks on the basis of sub-level accommodated by the last electrons when filling the available electrons into their various sub-levels.

Elements that are in Group IA and IIA are in the s-block

                                   Group IIIA to O are in the p-block

                                   Transition elements are in d-block

                                  Lanthanides and actinides are in the f-block

Uranium is in the actinide series.
