Two values of spin quantum numbers i.e., +1/2 and -1/2 represent.
A
Up and down spin of the electrons respectively
B
Two quantum mechanic spin states which refer to the orientation of spin of the electron
C
Clockwise and anti – clockwise spin of the electrons respectively
D
Anti – clockwise and clockwise spin of the electrons respectively.
Answer
Two quantum mechanic spin states which refer to the orientation of spin of the electron
Explanation
Solution
: Spin angular momentum of the electron, a vector quantity can have two orientations relative to the chosen axis. These two orientations take the values of +1/2 or
-1/2 and are called two spin states of the electrons.
