What is the electronic configuration of a 6+ chromium ion?
because its a 6+ ion, it has lost 6 electrons. therefore it will have the same electronic configuration as Ar (argon) - Ar is 6 before Cr on the periodic table. So it would be:
1s2 2s2 2p6 3s2 3p6
Cr Electron Configuration
It has lost its last 6 electrons, so the electron configuration would end with [Ar]
1s2 2s2 2p6 3s2 3p6 4s1 3d5 or [Ar] 3d5 4s1 completely half filled d-orbitals provide stability to the atom.It also explains +6 oxidation state of chromium as in potassium dichromate or potassium chromate
