Chloro compound of vanadium has only spin magnetic moment of $1.73\,BM$ . This vanadium chloride has the formula :- (at no. of $V = 23$ )
$VCl_4$
$VCl_3$
$VCl_2$
$VCl_5$
Assertion : Magnetic moment values of actinides are lesser than the theoretically predicted values.
Reason : Actinide elements are strongly paramagnetic.
$\mu = \sqrt{15}$ is true for the pair :-
