Question

What is uranium's electron configuration?

Answer 1

The electron configuration for Uranium (U) is based upon the placement of uranium in the fourth column of the actinide series or f block. Therefore th electron configuration for uranium must end as `5f^4`,

`1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5 p^6 6s^2 4e^14 5d^10 6p^6 7s^2 5f^4`

This notation can be written in core notation or noble gas notation by replacing the`1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5 p^6 6s^2 4e^14 5d^10 6p^6` with the noble gas [Rn].

`[Rn] 7s^2 5f^4`

I hope this was helpful.
