Helium (He) Helium is a colorless inert gas named after the sun (Greek, belios), because that is where it was first discovered. Liquid helium is used as a coolant in MRI instruments. [Pg.44]

For convenience, each element is given a chemical symbol that acts as a chemical shorthand in talking and writing about it and its reactions. The symbol always comprises one or two letters the first letter is a capital, which may correspond to the initial letter of the element s name Mg = magnesium, Ca = calcium, C = carbon, O = oxygen, H = hydrogen, S = sulphur, He = helium. Some chemical symbols are less obvious because they are derived from Latin names for the elements Pb = lead (plumbum), Fe = iron (ferrum), Na = sodium (natrium), K = potassium (kalium). [Pg.11]
