How many unpaired electrons are present in ground state of chromium ()? — Atomic Structure Chemistry Question

💡 Solution & Explanation

The ground state electronic configuration of Chromium (Cr, $Z=24$) is anomalous due to half-filled stability: $[Ar] 3d^5 4s^1$. It has 5 unpaired electrons in the 3d subshell and 1 unpaired electron in the 4s orbital, totaling 6 unpaired electrons. Therefore, correct answer is C.
