Question

An element 'M' belongs to '3d' series. Spin only magnetic moment in M2+ (+2 oxidation state of M) is highest among all +2 cation of 3d series. The group number of element M in modern periodic table is

Answer 1

HELLO DEAR,

All elements belongs to 3d-series are:-

Sc,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn.

In which Mn+2 have 5 unpaired electron.

By using the formula of magnetic moment ,

u=√n(n+2). Where n= no. of unpaired electron.

u=√5(5+2)

u=√35

u=5.92

Which is highest amongs all 3d-series element.

And its group no. is 7 (VII A)

I HOPE IT'S HELP YOU DEAR,

THANKS.
