The electron configuration of a chromium (Cr) 3 ion is Ar 3d3 4s0.
Vanadium ( V) has that configuration. Its atomic number is 23.
The electron configuration of a chromium II ion (Cr^2+) is [Ar] 3d^5. Chromium normally has an electron configuration of [Ar] 3d^5 4s^1, but when it loses two electrons to form the Cr^2+ ion, the 4s^1 electron is lost first, resulting in a 3d^5 configuration.
Iron has the electron configuration [Ar]3d64s2.
[Ar] 3d3Cr3+ has 18 core electrons, corresponding to the element Argon, and... 24 - 18 - 3 = 3 valence electrons.The noble gas electron configuration for chromium(III) ion is [Ar] 3d3.
Nickel has the atomic number 28 so it has the electron configuration 1s22s22p63s23p64s23d8 .
Vanadium ( V) has that configuration. Its atomic number is 23.

If it is an element, it could be either chromium (Cr) or molybdenum (Mo). You need to know more to know which. The electronic configuration for Cr is:[Ar]3d54s1and for Mo it is[Kr]4d55s1So both elements have 5 d-electrons and 1 s-electron. I'm not sure if that what you mean however by "s1d5"...

Mn
The electron configuration of the ion Cr(III)+ is 1s22s22p63s23p63d3
The electron configuration for Chromium (Cr) is [Ar] 3d^5 4s^1. The electron configuration for Chromium II (Cr^2+) is [Ar] 3d^4.
The element Ar 4s2 3d10 4p6 is Krypton (Kr).
The chromium (Cr) ion is expected to have 3 unpaired electrons. This is because the electron configuration of chromium is [Ar] 3d^5 4s^1, so when it forms an ion by losing its 4s electron, it retains the 5 unpaired electrons in the 3d subshell.
The atomic number of Cr, which stands for chromium, is 24.
