Question

what is the value of spin quantum number of electrons present in 4 f subshell

Answer 1

for 4f subshell is 1/2
An electron spins around an axis and has both angular momentum and orbital angular momentum.

Answer 2

Answer: 4f she'll contains 1/2 spin quantum numbers

Explanation:

As the electron in 4f she'll contains both angular momentum and another momentum which is anti clock wise and negative ....

Hope it helps......
