Neon has 8 electrons in its outer shell does it bond why or why not

It does, it will grow bigger and bigger

The valence (outermost) electron shells are shown. Click on the button to show or hide the inner orbital shells. A key characteristic of atoms is that they are most stable when they have full outer electron shells. Helium (He) has a full outer shell with two electrons; directly below it in the periodic table is Neon.
