Assertion: Magnetic moment of helium ato...

Assertion: Magnetic moment of helium atom is zero.
Reason: All the electron are electron are paired in helium atom orbitals.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Helium atom has paired electrons so their electron spin are opposite to each other and hence its net magnetic moment is zero.
