Noble gases are present in group 18 on the modern periodic table. Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Noble gases are not reactive. It was long believed that they could not form compounds. However since 1962 compounds of Ar, Kr, Xe and radon have been prepared. These are not stable.
They do not combine easily with other elements.
Novanet/Gradpoint answer: Low reactivity
They are all highly unreactive!

radioactivity, toxicity, instability, great atomic weight, great density, chemical reactivity, big atom diameter, etc.
Most dark-colored igneous rocks have a high density.

A common way to accessorize a bag is to add funky or brightly colored badges to the main fabric part of the bag to make it different and stand out from anyone else's.
No
They each have one valence electron in the outermost shell (or "orbital"). All the elements in Group 1 have this trait.
Reactivity to other substances, most notably.
They have similar properties as well as levels of reactivity
There are a great many common properties of matter. Flammability, density, and reactivity are just 3 common properties of matter.
it is less common
