1)
for given l, maximum number of orbital = (2*l+1)
each orbital can have 2 electrons.
So maximum number of electrons = 2*(2*l+1)
3s:
for s orbital, l=0
maximum number of electrons = 2*(2*l+1)
= 2*(2*0+1)
= 2
3d:
for d orbital, l=2
maximum number of electrons = 2*(2*l+1)
= 2*(2*2+1)
= 10
4p:
for p orbital, l=1
maximum number of electrons = 2*(2*l+1)
= 2*(2*1+1)
= 6
4f:
for f orbital, l=3
maximum number of electrons = 2*(2*l+1)
= 2*(2*3+1)
= 14
5f:
for f orbital, l=3
maximum number of electrons = 2*(2*l+1)
= 2*(2*3+1)
= 14
