[Ne] 3s23p2

In noble gas notation the simplification in the electron distribution to the orbitals is represented where in of all of the lower filled orbitals up to the closest noble gas is enclosed by its symbols in brackets. The remaining orbitals are written in the usual way. The electronic configuration of Si is 1s22s22p63s23p2. The electronic configuration of Ne is 1s22s22p6. Thus the Noble gas notation of silicon (Si) can be written as [Ne] 3s23p2.
