Question

The correct set of quantum numbers for the unpaired electron of F atom is (1)2,0,0,+1/2 (2)2,0,1,+1/2 (3)3,1,1,+1/2 (4)2,1,1,+1/2

Answer 1

Answer:

The answer is 2,1,1,+1/2

Explanation:

The electronic configuration of F atom is :

1s² 2s² 2p⁵

So n = 2, l = 1 and m = 1 because the unpaired electron is in the last orbital and the orbitals have values -1,0 and +1. And s=+1/2

Answer 2

The correct set of quantum numbers for the unpaired electron of the F atom is 2,1,1,+1/2.

• The electronic configuration of the F atom is as follows-
• ${1s}^{2} {2s}^{2} {2p}^{5}$
• In the F atom, there is one unpaired electron present in the 2p orbital.
• The value of a principal quantum number is n=2.
• The value of the azimuthal quantum number for the 2p orbital is l=1.
• As one unpaired electron is present so, s=1/2.
• Again the value of a magnetic quantum number is +1 to -1.
• Hence the correct option is 4.
