Question

transition element and there compounds exihibit paramagnetic behaviour​

Answer 1

Explanation:

The paramagnetic behavior is due to the presence of unpaired electron in (n-1)d orbital.

·The paramagnetic behavior increases as the number of unpaired electron increases.

·In 3d series, the paramagnetic behavior increases from beginning to the middle (Sc to Mn) and then decrease to zinc.

·The paramagnetism is expressed in magnetic moment µ.

·The value of µ increases as the number of unpaired electrons increases and consequently, paramagnetism also increases.

·√n(n+2) BM; where n=no. of unpaired electrons.

·For compound with 2 unpaired electrons-: mu=2√2=paramagneic

Answer 2

Answer:

• Transition metals show paramagnetic behaviour.
• Paramagnetism arises due to the presence of unpaired electrons with each electron having a magnetic moment associated with its spin angular momentum and orbital angular momentum.
• However, in the first transition series, the orbital angular momentum is quenched.
• Therefore, the resulting paramagnetism is only because of the unpaired electron.
