Answer:
8 electrons
Step-by-step explanation:
to solve this problem it is necesarry to take into account the nume of the other quantum number l, ml, and ms:
l: angular quantum number = l=n-1
ml: magnetic quantum number = ml=-l,...,0,...,+l
It is also neccesary to take into account each n state.
for n=1
- l=1-1=0
- ml=0
each ml state has two electrons with antiparallel spins. Hence, for n=1 you have 2 electron.
forn n=2
- l=2-1=1
- ml=-1,0,1
each ml state has two electrons. hence, for n=2 you have 3*2=6 electrons.
Finally, the total of electrons is 6+2=8
