the noble gases have their valence shell complete
All Nobel gases very rarely react, they are very stable gases as they have a full outer orbital. (on the far right of the table)
all the elements of group 18 are Nobel gases. They are very very less reactive.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
They share many properties, but one is that they all have 7 valence electrons.
The Nobel Gases are helium, neon, argon, krypton, xenon, and radon. They are located in Group 18 of the periodic table, also known as the noble gases or Group 8A. They are colorless, odorless, and generally inert gases with low boiling and melting points.
Except Nobel gases all other gases are molecular. The Nobel Gases, Family or Group 18 are atomic.
Non-metals, they are all gases.

One property of all gases is that they have no definite shape or volume. Gases expand to fill the container they are in, taking on the shape of that container. Additionally, gases are highly compressible and tend to diffuse and mix with each other easily.
It is atoms
Diffusion occur in all phases.
Their outer shells are all full, so they form compounds with great difficulty and when they do - IF they do; a couple of them won't - it's only with fluorine.
All gases have the ability to expand to fill their container, are compressible, and have low density compared to liquids and solids.
