Two elements found free in nature are helium(He) and gold(Au).
There are many other elements found free in nature, they are:-
Carbon (C)
Nitrogen (N)
Oxygen(O)
Sulphur (S)
The inert gases, Neon, Argon , Krypton, Xenon, Radon.
Helium (He)
Physical : inert gas; condensing point ~ 4K; freezing point ~ 2K; exists in trace amounts in the atmosphere; obtained by condensing the other atmospheric gases out. Exists as monatomic atoms.
Uses: any reaction requiring a 'lighter than air' inert atmosphere.
Gold(Au)
Physical : relatively inert soft yellow metal found 'native' - as nuggets; dense heavy metal. Good conductor of electricity.
Uses: Jewellery; space exploration.
