Give the long configuration for Uranium
WRITE ANSWER WITH THE FOLLOWING FORMAT
1s2 2s2.........etc

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 the electron configuration for uranium must end as 5f4,

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4e14 5d10 6p6 7s2 5f4

This notation can be written in core notation or noble gas notation by replacing the : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4e14 5d10 6p6 with the noble gas [Rn].

[Rn] 7s2 5f4

I hope this was helpful.
