How many electrons can have s+1//2in a d-sub-shell?

1.	How many electrons can have s+1//2in a d-sub-shell?
Answer» SOLUTION :d' SUB-shell has FIVE orientations. Each ORIENTATION can accommodate one electron with SPIN quantum number `+1//2` and another electron with `-1//2`. Hence number of electrons with `s+1//2` in 'd' sub shell is 5
