They complete the Octet Rule. Meaning that they have 8 electrons in their outershell which makes them unwilling to covalently bond with other molecules, this is why they are called inert.

Properties Of Noble Gases

The six noble gases are found in group 18 of the periodic table. These elements were considered to be inert gases until the 1960's, because their oxidation number of 0 prevents the noble gases from forming compounds readily. All noble gases have the maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others), making them stable.
* Helium
* Neon
* Argon
* Krypton
* Xenon
* Radon

1. They have 8 valence electrons, therefore they are at the perfect level and do not need to bond to get more, or get rid of electrons. Because of this, they don't react, and that's why they're also called the inert gases. 2. Metallic bonds are unique because the valence electrons in the metal just float around the atoms, like a sea of electrons, this gives metal it's ductility, maleability, and conductivity. 3. A molecule is a set of bonded atoms, while a formula unit is used for ions, because since they don't bond, they can't be defined as molecules. for example, salt's formula unit is NaCl, but that's not a molecule because they aren't bonded. 4. Valence electrons are the ones involved in chemical bonds.

Except Noble gases no any element has completely filled outtermost shell. This is unique thing.

Their molecules are monoatomic, as they do not readily combine with other elements, including themselves (however they DO combine with other atoms if the conditions are made exceptional, so they are not totally inert), this makes them having a very low boiling point, they will liquify only at very low temperature. For all intents and purposes, it can be taken that they will not participate in chemical reactions.

They do not react with other atoms. The outermost electron shell in the atom are filled, so the atom is happy and stable and doesnt want to share its electrons, i.e. make chemical bonds with other atoms to form compounds

Their last orbit is filled with 8 electron except helium which has two so they have no affinity to other atom for any chemical bondage

Noble gasses have stable electron configuration. That is eight electrons in the valence shells.
