The calculated spin only magnetic moment of Cr 2 + ion is
Text Solution
Verified by ExpertsThe correct answer is:
NOT FOUND
Electronic configuration of Cr - [Ar] 3d 5 4s 1
Electronic configuration of Cr 2+ - [Ar] 3d 4 
Number of unpaired e- = 4
Spin only magnetic moment is calculated by = 
n = number of unpaired e- is calculated by-
So, Spin only magnetic moment = 
= 4.90BM
