Why is that sometimes an element symbol is not the first letter of its name?
Element symbols are based on the Latin names for the elements. In cases where two elements have names that start with the same letter, the symbol uses the first and sometimes the second letter of the name to differentiate them. For example, "Sodium" and "Sulfur" both start with 'S,' so their symbols are Na and S, respectively.
Why do some symbols have one letter some have two letters and some have three letters?
Elements are give symbols consisting of letters, and these are related to the names of the elements (in some language at some date). There are 26 letters in many alphabets, but more than four times that number of elements. So it is necessary to use some mechanism to distinguish among elements with names that start with the same letter. Adding numbers is done to designate the number of atoms in a compound, the isotope, and so on. The best solutions is to use pairs of letters for most elements.
