In a borax bead test under hot condition, a metal salt (one from the given) is heated at point B of the flame, resulted in green colour salt bead. The spin-only magnetic moment value of the salt is _______ BM (Nearest integer)
[Given atomic number of \(\mathrm{Cu}=29, \mathrm{Ni}=28, \mathrm{Mn}=25, \mathrm{Fe}=26\)]
Solution
$\mathrm{Fe}^{+3}$ will give green coloured bead when heated at point B.
Number of unpaired $\mathrm{e}^{-}$in $\mathrm{Fe}^{+3}=5$
$\mu=5.92$
Nearest integer $=6$
