How to Find the Valence Electrons for Chromium (Cr)?
https://valenceelectrons.com/valence-electrons-of-chromium/
WebHere, the electron configuration of chromium ion (Cr 2+) is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 4. This electron configuration shows that chromium ion (Cr 2+) has three shells and the last shell has twelve electrons. Therefore, chromium ion (Cr 2+) has a total of twelve valence electrons. Cr – 3e – → Cr 3+.
