List of the chemical elements after symbol


the chemical elements and their connections are usually written as formula with standard symbols. These symbols and the way of writing of the element names are specified of the IUPAC (international union OF pure one and Applied Chemistry)and regularly examines. The element symbols are listed alphabetically in the following.

Examples of the symbol way of writing:

H 2 O - water
KCl - Kaliumchlorid
NaCl - sodium chloride (food salt)
