Question
The corrent ground state electronic configuration of chromium atom is :
Options
A.[Ar] 3d5 4s1
B.[Ar] 3d4 4s2
C.[Ar] 3d6 4s0
D.[Ar] 3d6 4s1
Solution
Expected configuration 3d4. 4s2 is less stable than 3d5 4s1, which is more stable due to half-filled sub-shells. 3d5, 4s1 configuration is supported gy magnetic moments also.
