Question

If the substance having two unpaired electrons, the value of Het is
1.732 BM
0
B
2.83BM
o
o
3.87BM
o D
5.92BM​

Answer 1

Answer:(B)2.83

Explanation:

Let, no. Of unpaired electrons= n

Square root of [n(n+2)] =

Square root of [ 2(2+2) ] = 2.83 BM

Answer 2

If the substance having two unpaired electrons, the magnetic moment value of He is 2.83BM

Explanation:

• Given the number of unpaired electrons are 2
• let n be the number of unpaired electrons
• The Magnetic moment of the element is determined with the help of a formula $\sqrt{n(n+2)}$
• On substituting the value of n in the formula we get
• Magnetic moment =$\sqrt{2(2+2)}$
• Magnetic moment =$2.83BM$
• Unit of magnetic moment is Bohr magneton(BM)
• The Magnetic moment is the property of a magnet which interacts with the applied force for giving magnetic moment.
• It is the magnetic strength and the orientation of the magnet which produces magnetic field.
