Helium Interesting Facts |
- Helium was first discovered by Sir William Ramsay in London and independently by P.T. Cleve in Sweden in 1895.
- Helium gas is a colourless, odourless and tasteless inert gas. It makes up about 0.0005% of the air we breathe.
- Helium has some unusual properties when it is very cold. It can conduct electricity and heat with almost no resistance and can even flow up the walls of containers and escape!
- Helium is a natural substance and is produced by radioactive decay in rocks.
- Helium is so named because it was first detected in light patterns in the sun (Greek helios) before it was detected on earth.
