Periodic Table Symbols
Each element in the Periodic Table has been given a 1, 2 or 3 letter symbol collectively called Periodic Symbols. The first letter of the Periodic symbols is always a capital letter, for example, H for hydrogen, C for carbon, N for nitrogen. If there is a second letter or third letter in the symbol it is a lower case letter for example, He for Helium, Uuh for Ununhexium.
In 1828 Jakob Berzelius developed a table of atomic weights & introduced letters to symbolize elements, called Periodic Symbols. Each Chemical element is given a unique chemical symbol using abbreviations of their names which are used & recognised all over the world. Chemical symbols of elements come from their English, Greek or Latin names for example the Periodic symbol for Gold is Au from the Latin word 'aurum' meaning gold.
