Explanation:
As it is known that an atom having principal quantum no n=4 has32 electrons(max. no of -e's in nth shell=2n. n ).. So only 16 electrons having m subscript s=-1/2 would be there in an atom having principal quantum no n=4.

Answer:
Explanation:
When principal quantum number=4, electrons are 4s,4p,4d,4f.
In these orbitals,half electrons will have spin quantum number=+1/2 and other half -1/2.
Total electrons in:-4s=24p=64d=104f=14
With -1/2 spin,number of electrons will be halved in all four types of orbitals.
So, number of electrons=1+3+5+7=16
