A transition elements with atomic number 24 will have its magnetic moment
- A \(5.92 \mathrm{BM}\)
- B \(6.93 \mathrm{BM}\)
- C it will be diamagnetic
- D it will be more than \(8 \mathrm{BM}\)
Answer & Solution
Correct Answer
(B) \(6.93 \mathrm{BM}\)
Step-by-step Solution
Detailed explanation
Outer electronic configuration of the element with atomic number 24 is \(3 d^{5} 4 s^{1}\). Number of unpaired electrons \(=6\) \[ \begin{aligned} \mu &=\sqrt{n(n+2)} \mathrm{BM}=\sqrt{6(6+2)}=\sqrt{48} \\ &=6.928=6.93 \mathrm{BM} \end{aligned} \]
