Considering the extra stability of half-filled subshells, what is the ground state electronic configuration of a Chromium (Z=24) atom?
Q1. Considering the extra stability of half-filled subshells, what is the ground state electronic configuration of a Chromium (Z=24) atom?
Answer: [Ar] 4s1 3d5
Explanation: Chromium adopts a 4s1 3d5 configuration for extra stability; 4s2 3d4 is the expected but incorrect ground state configuration.
