In which block of the periodic table is uranium (u) found?
o s block
od block
p block
f block

f-block

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.

answer; i believe that the correct answer is (a) potassium(k)

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
