How many unpaired electrons are in the electron structure of 24 Cr, [Ar]4s1 3d5 Answer the questions below for an element that has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s1. A. What is the symbol for this element? B. What is the atomic number of this element? C. The electronic configuration of Mn+2 is 3d5 because in the last subshell of Mn is 3d5,4s2; so the ejection of electron from the outer most subshell so the energy of 4s subshell is lower than 3d subshell on the basis of rule (n+l) rule. 2011-08-25 Start studying irregular electron configurations.

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.
