​Earlier symbols for chemical elements stem from classical Latin and Greek words. For some elements, this is because the material was known in ancient times, while for others, the name is a more recent invention.
For example, Pb is the symbol for lead (plumbum in Latin);
Hg is the symbol for mercury (hydrargyrum in Greek);
and He is the symbol for helium (a Neo-Latin name) because helium was not known in ancient Roman times.
Some symbols come from other sources, like W for tungsten (Wolfram in German) which was not known in Roman times.

​1 H Hydrogen Greek elements hydro- and -gen, meaning 'water-forming'
2 He Helium Greek hḗlios, 'sun'
3 Li Lithium Greek líthos, 'stone'
4 Be Beryllium beryl, a mineral (ultimately from the name of Belur in
southern India)
5 B Boron borax, a mineral (from Arabic bawraq)
6 C Carbon Latin carbo, 'coal'
7 N Nitrogen Greek nítron and -gen, meaning 'niter-forming'
8 O Greek oxy- and -gen, meaning 'acid-forming'

​

​Chapter 2

​Symbols for chemical elements, also known as atomic symbols, normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalized.

A three-letter temporary symbol may be assigned to a newly synthesized (or not yet synthesized) element. For example, "Uno" was the temporary symbol for hassium (element 108) which had the temporary name of unniloctium, based on the digits of its atomic number. There are also some historical symbols that are no longer officially used.
