THE NOBLE GASES
- Are in group 8 (or 0) of the periodic table.
- They are inert.This means it is very difficult to get them to react with anything.
- all these elements have a FULL OUTER SHELL!!!!!!!!
- Because of this, it is very hard to get them to react with anything.
USES OF THE NOBLE GASES
They are useful because they are unreactive.
-Argon and Helium are used in welding, the form a blanket over the hot metal to stop it reacting with oxygen.
-Argon is used in fire-extinguishing systems because it is NON-FLAMMABLE.
-Helium has a low density, so is used for filling balloons and airships (it floats)
-Neon is often used in fluorescent lamps and advertising displays- it produces a red coloured light when electricity is passed through it.
