What is the electron configuration for U?

Answer 1

1s²

2s² 2p6

3s² 3p6 3d10

4s2 4p6 4d10 4f14

5s2 5p6 5d10 5f4

6s2 6p6

7s2

Edited by Progassman from this point on:

The diagram above is not the electron configuration of Uranium (U). It is the Aufbau Principle with the number of electrons it can hold in every sublevel. The real configuration is 1s2,2s2 2p6,3s2 3p6 3d10, 4s2 4p6 4d10, 5s2 (from here on, I am not sure but I am sure about the short hand) 5p6 5d10 5f3, 6s2 6p6 6d1, 7s2. The short hand method is [Rn] 5f3 6d1 7s².

Answer 2

The electron configuration for Uranium (U) is [Rn] 5f3 6d1 7s2.
