The two electrons in sub-shell of K-shell will differ in:

A

Same principle quantum number

B

Same azimuthal quantum number

C

Same magnetic number

D

Same spin quantum number

Text Solution

Verified by Experts

The correct Answer is:
D
K-shell refers to the first shell. The capacity of this orbit is to carry a maximum of two electrons in opposite spin as shown `(uarr darr)`. So, in any case the two electrons cannot have the same value of spin quantum number. One electron will have to
have a value of `+ (1)/(2)` and the other `-(1)/(2)`
