Question

Name the metal of 1st row transition series that has highest value for magnetic moment

Answer 1

Answer:

It must be chromium....with outer configuration 3d5 4s1

it has the most no of unpaired electrons........6 unpaired electrons.......

spin only magnetic moment is given by the expression ų= root of (n(n+2)) where n is the no of unpaired electons

Answer 2

Magnetic moment = n(n+2)

Where n is the number of unpaired electrons. Maximum the value of unpaired electron, greater the value of magnetic moment. So,3d

5

has highest value of magnetic moment.
