Chemical symbols are these days given 1-, 2- or 3-letter symbols based on some letters in their name or name in Latin. For example H is Hydrogen, Ca is calcium and Uuo is Ununoctium. Or, from the Latin names, Fe is Iron, K is Potassium and Ag is Silver. It appears that different symbols were used in the past, rather like diagrams that are used for the planets or male and female symbols.
