1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d8 What element is represented by the ground state electron configuration shown above?

Pd (palladium).

Explanation:

46 electrons total, this is representative of the Pd (palladium) element.

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.
