Noble Gasses
By Owen Poland
Introduction
Noble gasses are found in group 8 on the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and element 118 (temporarily named ununoctium [Uuo]).

Common properties
Common properties of noble gasses are properties that each of them have the same. First off they are all non-metals, hence why they are called noble GASSES. Secondly they are very unreactive. This is because a reaction takes place when two elements trade electrons to complete their valence shell. However with a noble gas their valence shell is already complete, therefore they cannot trade electrons to complete their valence shell. Thirdly they are colourless and finally they exist as single atoms so they do not come in diatomic state, this is called monatomic.
