When instead of referring to a particular chemical element, the group of chemical elements is referred then they are represented with a set of general symbols not used for names of the specific chemical elements. Look at the interesting table below: Name of the element In some cases, the chemical elements have symbols as per their ancient, Latin, Greek, Arabic or German names. In the table given below look and try to differentiate the chemical elements as per their second letter in the symbol. Look at the following examples in the table for simple one-letter symbols. For example, Copper with the symbol ‘Cu’ and Chlorine with the symbol ‘Cl’ have the same first letter ‘C’ as the same but their second letter (‘u’ and ‘l’) is different which help to differentiate both the chemical elements. In few cases, the first letter in the symbol can be the same but the second letter can be never the same. It is important to remember that no two elements have the same symbols to represent them.The symbols have the first letter of their name in uppercase and the second letter in lowercase.For example, the element Hydrogen is symbolized with ‘H’, Helium with ‘He’, Oxygen with ‘O’ and Carbon with ‘C’. Every chemical element like Hydrogen, Helium, Oxygen or Carbon has unique letters to represent them called Symbols.Thus with the advancement of chemistry hundreds of the chemical elements had been discovered and today all those 118 elements have a unique symbol to represent them. The general idea behind giving symbols to the elements was that even though these elements names were written differently in different languages these symbols played a common role in representing each of the chemical elements.
