Question

What is the ground-state electron configuration of `Pb`?

Answer 1

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`
