The orbital diagram for Nitrogen is 1s 2s 2p. The orbital diagram for chlorine is 1s 2s 2p 3s 3p. The orbital diagram for sodium is 1s 2s 2p 3s 3p and the orbital diagram for neon is 1s 2s 2p.
The short-hand electron configuration is a way of writing the electron configuration of an element that uses the noble gas core. The noble gas core is the electron configuration of the nearest noble gas to the element in question. For example, the noble gas core of neon is 1s²2s²2p⁶.
The orbital diagram shows how the electrons are distributed in the different orbitals around the nucleus of the atom. Each orbital can hold up to two electrons.
