Atoms, like Neon (Ne), that have the s and p sublevels filled with either electrons are said to have an "octet" of electrons.
stable and chemically nonreactive, or inert.
it has a full octet
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Neon, Xenon, Argon
Atoms whose outer shell is filled have eight valence electrons and belong to Group XVIII. This group is known as the noble gases.

In chemistry, the octet rule states that an atom has eight electrons in its outer shell. When all eight electron orbitals are filled, the atom is described as non-reactive. Examples include neon and argon.

they become stable as they have completely filled outermost valence shell and if they have no electron in their outermost shell they become non reactive.
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
The noble gasses all have a filled outer electron shell of eight electrons, except helium which has two electrons. Since their outer electron shells are filled, they are less likely to react with other atoms.
