Question

11. What is the Electron Configuration for Pb?

Answer 1

- First, to write the Electron Configuration for Pb, we need to know the total number of electrons in the Pb atom. We can take that information from the Periodic Table of Elements:

Electrons in the Pb atom = 82

- Second, we complete the orbitals with the electrons following the Möller diagram:

`\begin{gathered} 1s^22s^22p^63s^23p^64s^23d^(10)4p^65s^24d^(10)5p^66s^24f^(14)5d^(10)6p^2 \\ \\ \end{gathered}`

That is the complete Electron Configuration for Pb.
