Question

magnetic properties of d-block element explain deeply

Answer 1

Answer:

Elements of d-block when kept in external magnetic field are attracted or weekly repel.

• Element which is attracted is called Paramagnetic substances.
• Elements which are repel are called Diamagnetic substances.

Reason-

Element having unpaired electron are attracted due to the magnetic moment produced by the electron spin on to the axis. This magnetic moment depends on number of unpaired electron.

$Magnetic \ moment = M$

$\mu = \sqrt{n(n-1)}$

where, n= number of unpaired electrons.

and unit is Bohr magneton
