Answer:

The ground-state electron configuration of #"Pb"# is:

#["Xe"]"4f"^(14)"5d"^(10)"6s"^2"6p"^2#

Explanation:

Lead #("Pb")# has atomic number #82#. This means that all atoms of lead have #82# protons in their nuclei. In a neutral lead atom, there will also be #82# electrons in the electron cloud. The ground-state electron configuration of #"Pb"# is:

#["Xe"]"4f"^(14)"5d"^(10)"6s"^2"6p"^2#
