Q: -->Given below are two statements : <table border="1" cellpaddi...

Hint: The electronic configuration of \(Cr^{2+}\) is \([Ar]3d^4\) Explanation: (i) Ferromagnetic materials exhibit orders-of-magnitude stronger magnetization due to the exchange interaction, a quantum mechanical effect that aligns electron spins in parallel across large domains. Paramagnetic alignment is weaker and limited to individual atoms/molecules. Substances that are attracted very strongly in an applied magnetic field are termed "ferromagnetic". In fact, ferromagnetism is an extreme form of paramagnetism. (ii) The electronic configuration of \(Cr^{2+}\) is \([Ar]3d^4\) and of \(Nd^{3+}\) is \([Xe]4f^3\) . So, the number of unpaired electrons in \(Cr^{2+}\) and \(Nd^{3+}\) are 4 and 3, respectively. Both have different numbers of unpaired electrons. Hence, option 1 is the correct answer.

Hint: The electronic configuration of

Cr%5E%7B2%2B%7D

%5BAr%5D3d%5E4

Explanation:

(i) Ferromagnetic materials exhibit orders-of-magnitude stronger magnetization due to the exchange interaction, a quantum mechanical effect that aligns electron spins in parallel across large domains. Paramagnetic alignment is weaker and limited to individual atoms/molecules.

Substances that are attracted very strongly in an applied magnetic field are termed "ferromagnetic". In fact, ferromagnetism is an extreme form of paramagnetism.

(ii) The electronic configuration of

Cr%5E%7B2%2B%7D

%5BAr%5D3d%5E4

and of

Nd%5E%7B3%2B%7D

%5BXe%5D4f%5E3

. So, the number of unpaired electrons in

Cr%5E%7B2%2B%7D

and

Nd%5E%7B3%2B%7D

are 4 and 3, respectively. Both have different numbers of unpaired electrons.

Hence, option 1 is the correct answer.

Statement I:	Ferromagnetism is considered as an extreme form of paramagnetism.
Statement II:	The number of unpaired electrons in a $Cr%5E%7B2%2B%7D$ ion (Z = 24) is the same as that of a $Nd%5E%7B3%2B%7D$ ion (Z = 60).

1.	Statement I is True but Statement II is False.
2.	Statement I is False but Statement II is True.
3.	Both Statement I and Statement II are True.
4.	Both Statement I and Statement II are False.
