NEET2025Chemistryd and f Block ElementsActual
Given below are two statements : Statement I : Ferromagnetism is considered as an extreme form of paramagnetism. Statement II : The number of unpaired electrons in a Cr ²⁺ ion ( Z =24) is the same as that of a Nd ³⁺ ion (Z=60) . In the light of the above statements, choose the correct answer from the options given below :
Options
- ABoth Statements I and Statement II are true
- BBoth Statement I and Statements II are false
- CStatement I is true but Statement II is false
- DStatement I is false bt Statements II is true
Correct answer
C. Statement I is true but Statement II is false
Step-by-step solution
Ferromagnetism > Paramagnetism Statement-I is true Cr ⁺²=3 ~d ^4 4 unpaired electrons Nd ⁺³=4 f ^3 3 unpaired electrons Statement-II is false.
