What is the electron configuration of neon?

The electron configuration for Neon (Ne) is 1s2, 2s2, 2p6.

The reason behind this electron configuration is that Neon (Ne) has a total of 10 electrons. Hence, to hold 10 electrons an atom must possess 2 shells. The first shell can hold up to 2 electrons, no more. The second shell can hold up to 8 electrons, no more. The first shell consists of the sub-shell 1s, while the second shell consists of the sub-shell's 2s and 2p. S sub-shells can hold a maximum of 2 electrons only. And P sub-shells can hold a maximum of 6 electrons. Hence, in order we get 1s2, 2s2, and 2p6; which totals 10 electrons.
