Calculate the number of electrons in energy level 1.
Energy level 1has the s sub level, which means there are no more than 2 electrons
Calculate the number of electrons in energy level 2.
Energy level 2 has the s sub level and the p sub level, so 2 + 6 = 8, which means there are no more than 8 electrons
Calculate the number of electrons in energy level 3.
Energy level 3 has the s sub level, the p sub level and the d sub level, so 2 + 6 + 10 = 18, which means there are no more than 18 electrons
Calculate the number of electrons in energy level 4.
Energy level 4 has the s sub level, the p sub level, the d sub level and the f sub level, so 2 + 6 + 10 + 14 = 32, which means there are no more than 32 electrons
What is the electronic configuration for Ne?
1s2 2s2 2p6
