Quick Answer: What Element Is AR 4s2 3d7?

What element has the electron configuration AR 4s1?

Why chromium has electron configuration 4s1 3d5.

– Quora..

What element is 6s2?

Barium1 Answer. Ernest Z. Barium has the noble gas configuration [Xe]6s². To work backwards and find the element with a given configuration, you first find the noble gas in the Periodic Table.

Why is CU AR 4s1 3d10?

Re: Chromium and Copper Therefore one electron from 4s2 is removed making Cr [Ar] 3d5 4s1. Same is the case with Cu, it would be [Ar] 3d9 4s2, but again it would be more stable if the d shell is completely filled with 10 electrons, instead of 9. Therefore and electron from s is removed making Cu it [Ar] 3d10 4s1.
