Lead would have a standard electron configuration of

1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4f ^14 5d^10 6p^21s22s22p63s23p64s23d104p65s24d105p66s24f145d106p2

The noble gas in the row above lead is xenon.

We can replace 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^61s22s22p63s23p64s23d104p65s24d105p6 with the symbol [Xe] and rewrite the noble gas configuration of lead as

[Xe] 6s^2 4f ^14 5d^10 6p^2[Xe]6s24f145d106p2

I hope this was helpful.
