Question

A d-block element has total spin value of +3 or -3,then the magnetic moment of element is approximately
a.2.83B.M
b.3.87B.M
c.5.9B.M
d.6.93B.M​

Answer 1

Answer:

Explanation:

To calculate the spin magnetic moment(M) we can use the formulae of M=✓(s(s+2)).

Where the s is the spin values for the metals or the transition or d-block elements which in case is here.

To calculate we need to know the value of s such that the value inside the square root remains positive.

So, to make the value positive we have to take the value of spin to be +3 then we can use the formulae M= ✓(s(s+2)).

M=✓(3(3+2)).

M= ✓15.

M=3.87B.M.

Answer 2

Answer: D -6.93 BM

Explanation:

The magnetic moment of an element can be found out using the formula :

root (4s(s+1))

Where s is the total spin of an atom
