Answer

Brief Explanations:

Lead (Pb) has an atomic number of 82. The noble - gas that precedes lead in the periodic table is radon (Rn) with an atomic number of 86. We use the electron - configuration of the previous noble gas (Rn) as a core. Then we add the remaining electrons. The electron configuration of lead beyond the radon core is $6s^{2}4f^{14}5d^{10}6p^{2}$.

Answer:

[Rn]$6s^{2}4f^{14}5d^{10}6p^{2}$
