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 Cr2+\mathrm{Cr}^{2+} ion (Z=24)(\mathrm{Z}=24) is the same as that of a Nd3+\mathrm{Nd}^{3+} ion (Z=60)(Z=60). In the light of the above statements, choose the correct answer from the options given below :

Options

  1. ABoth Statements I and Statement II are true
  2. BBoth Statement I and Statements II are false
  3. CStatement I is true but Statement II is false
  4. 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 d4\mathrm{Cr}^{+2}=3 \mathrm{~d}^4 4 unpaired electrons Nd+3=4f3\mathrm{Nd}^{+3}=4 \mathrm{f}^3 3 unpaired electrons Statement-II is false.
