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
