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.
The electron configuration of chromium III ion using noble gas notation is [Ar] 3d^3. Chromium III ion has lost three electrons from its neutral state, which results in the electron configuration of [Ar] 3d^3.
The element with the electron configuration 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8 is Chromium (Cr).
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"...
The element with the electron configuration 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8 is Chromium (Cr).
Mn
No, chromium is not a noble gas. It is a transition metal with the atomic number 24 and is commonly used in the production of stainless steel and other alloys.
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.
