Selenium. 78.96 [Ar] 4s2 3d10 4p4. Bromine [Ar The correct answer to the question “What is the electron configuration for chromium?” is letter B or 1s2 2s2 2p6 3s2 3p6 421 3d5. The actual electron configuration of Cr is [AR] 4s1 3d4 and Cu is [Ar] 4s1 3d10. Now, Letter A or 1s2 2s2 2p6 3s2 3p6 4s2 3d4 is the expected electronic configuration of a chromium since it has 24 electrons.

Answer: compare to copper. is [Ar] 3d94s2 least stable than Ar 3d10 4s1.bcoz in Ar 3d10 4s1 the s orbital was half filled and d orbital was fullfilled . the half filled and full filled electronic configuration was more stable .

As configurações eletrônicas  Copper should have the configuration (Ar) 3d9 4s2, but one of the 4s electrons is donated to the 3d sub shell for Copper to become (Ar) 3d10 4s1. This is  U - (Ar) 3d1 4s2. V - (Ar) 3d2 4s2. W - (Ar) 3d3 4s2.
