What is Group 0: Noble Gases?
Within Chemistry, which covers atoms, bonding, reactions, the periodic table, organic chemistry and the chemistry of everyday life, this topic explains Group 0: Noble Gases. Chemistry links what you can see in the lab to the particles and bonds behind it, so each topic here shows that link in a model.
Check that you can explain Group 0: Noble Gases in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Group 0: Noble Gases helps you explain why substances behave as they do, from cleaning products and food to medicines.
Group 0: Noble Gases in detail
The noble gases (helium, neon, argon, krypton, xenon, radon) have full outer shells of electrons, so they are very unreactive and exist as single atoms. They are colourless gases with very low boiling points that rise slightly down the group.
Helium is used in balloons because it is less dense than air and non-flammable, neon in advertising signs, and argon in filament bulbs and welding to provide an inert atmosphere. Their stability is the reason other elements react: atoms gain, lose or share electrons to reach the same stable arrangement.
