Electronic configuration of Cr2 + ion? 3
What is the electron configuration of Cr2 + ion (chromium 2+)?

The inner electrons are only the center of the Ar, i.e. 1s2 2s2 2p6 3s2 3p6. So we really only need to take care of the valence electrons:
Cr is in column 6 of table ic, but since it is a 2+ ion, 2 is missing, so there are a total of 4 valence electrons. We have 4s subs and 3d subs to insert electrons, but the general rule is that if a transition metal ion is missing 2 or more from its neutral state, you need to remove two electrons before 4s subs. Because they are the outermost part of the atom.
Therefore, the ground state electron configuration for Cr2 + ion is [Ar] 3d4.

What is the electron configuration of Cr2 + ion (chromium 2+)?
Cr electron ss = K2, L8, M13, N1
Cr2 + ions = K2, L8, M12
Chromium is one of the exceptions where you first get rid of the highest energy levels.
Instead of writing Cr:
[Ar] 4s2 3d4
Cr is: [Ar] 4s1 3d5
However, since it is Cr2 +, you must get rid of the two electrons (first with the higher number of energy levels, then with the higher energy level (s p d f)).
Cr2 +: [Air] 3d4

1s2, 2s2, 2p6, 3s2, 3p6, 3d4
Cr + 2 loses its 4s electron to ionize.
Like cr but with 2. minus
Sorry, can't write. I did chemistry 2 years ago and forgot.
c) Paramagnetic with four non-paired electrons.
