प्रश्न
Calculate magnetic moment of thorium (Z=90). Is this element diamagnetic or paramagnetic?
Advertisements
उत्तर
The electronic configuration of thorium is [Rn] 5f0 6d2 7s2.
the condensed electronic configuration for its divalent cation will be
There are 2 unpaired electrons, so n = 2.
`therefore mu = sqrt(2 (2 + 2)) = sqrt8` BM = 2.83 BM
Spin only magnetic moment of the given ion is 2.83 BM. This element contains two unpaired electrons and hence, it is paramagnetic.
