LEAD - WIKIPEDIA
A lead atom has 82 electrons, arranged in an electron configuration of [Xe]4f 5d 6s 6p . The sum of lead's first and second ionization energies—the total energy required to remove the two 6p electrons—is close to that of tin, lead's upper neighbor in the carbon group. This is unusual; ionization energies generally fall going down a group, as an element's outer electrons become more distant fro…
