Q.
Among $V (Z = 23), Cr (Z = 24), Mn (Z = 25) $which will have highest magnetic moment.
Structure of Atom
Solution:
Electronic configuration of ultimate and penultimate shell in ground state of these elements is as follows:
Magnetic moment $m = \sqrt{N\left(N+2\right)}$ Bohr magneton where
$N$ is number of unpaired electrons, $m$ will be highest for $Cr$ having $6$ unpaired electrons
