The 'spin only' magnetic moment value of (MO_4 ^ 2- ) is _______...

The 'spin only' magnetic moment value of (\mathrm{MO}_4{ }^{2-}) is _______ BM. (Where M is a metal having least metallic radii. among (\mathrm{Sc}, \mathrm{Ti}, \mathrm{V}, \mathrm{Cr}, \mathrm{Mn}) and (\mathrm{Zn}) ). (Given atomic number: (\mathrm{Sc}=21, \mathrm{Ti}=22, \mathrm{~V}=23, \mathrm{Cr}=24, \mathrm{Mn}=25) and (\mathrm{Zn}=30))

Correct answer

0

Step-by-step solution

Metal having least metallic radii among Sc,Ti,V\mathrm{Sc}, \mathrm{Ti}, \mathrm{V}, Cr,Mn&Zn\mathrm{Cr}, \mathrm{Mn} \& \mathrm{Zn} is Cr\mathrm{Cr}. Spin only magnetic moment of CrO42−\mathrm{CrO}_4^{2-}. Here Cr+6\mathrm{Cr}^{+6} is in d0\mathrm{d}^0 configuration (diamagnetic).
