- They have an octet configuration with their outermost s and p-sub-levels full, which makes them inert or nonreactive.
- The s-sub-level takes up a maximum of 2 electrons while the p-sub-level holds a maximum of 6 electrons.
- They include, argon, neon, xenon, krypton, etc.
- Their electron configuration shows full outermost s and p-sub-levels.
- For example; the electron configuration of Ne is 1s²2s²2p⁶, with full s and p sub-levels.
