= Helium  =

Helium's atomic number is 2. This means helium has 2 electrons and 2 protons. Out of the 118 elements in the periodic table, helium has the lowest melting point of all.

Heliums melting point(when the substance turns from solid to liquid) is -272.0°C. The boiling point (when the liquid turns into a gas) of helium is -268.6°C

Helium is colourless, tasteless and odourless. The word helium originates from the Greek word 'helios' meaning sun. The symbol for helium is He. Helium is used as a treatment for people suffering from asthma. Helium is formed underground. It would take 6,000 baloons of helium to lift a 37.5kg child off the ground. Helium is non-toxic. There is no helium existing in the human body. In the universe, 11.3% of the atoms are Helium. Helium was discovered in 1868 by Pierre Jansen, a French astronomer. Helium is a Noble gas because it does not react with other chemicals.

It is very light; the only element that weighs less than helium is Hydrogen. The sun and stars are made mostly of helium. Helium is only ever found in the state of gas.
