the elements get their symbols through the number of protons (or electrons) which is the atomic number. The mass number comes form the number of neutrons + protons =] electrons have no relative mass (0.0005(zero))
From their (Latin) names or scientist's names:
O - Oxygenium
H - Hydrogenium
S - Sulfur
Au - Aurum
Ag - Argentium
scientists:
Rutherfordium
Mendelevium
Einsteinium
etc
Elements get their symbols mainly from their names. This is not always the case though. Sometimes it is from Latin etc.
As an example, Pb is the symbol for Lead and where the name plumber comes from and is Latin. Ag for silver and Au for gold similarly. S for sulfur and O for oxygen are a bit more obvious. The names these days are set internationally by IUPAC. The International Union of Pure and Applied Chemists.
Ce is the chemical symbol for cerium.
The symbol for magnesium on the periodic table of elements is Mg
There is no symbol for Al2O3 as it is a compound, chemical symbols are for elements
uranium
Sn is tin.
Helium, along with the other elements, gets its symbol from the Latin and not from English.
