How many electrons in Sulphur (z = 16) can have n + l = 3 ?

Answer»

16S = 1s2 , 2s2 ,2p63s2 ,3p4

for 1s2 , n + l = 1 + 0 = 1

for 2s2 , n + l = 2 + 0 = 2

for 2p6 , n + l = 2 + 1 = 3

for 3s2 , n + l = 3 + 0 = 3

for 3p4 , n + l = 3 + 1 = 4

Thus n + l = 3 is for 2p6 and 3s2 electrons, i.e., for 8 electrons.
