What are the symbols for the elements in the periodic table?
If you look at the periodic table (go to webelements.com to see one if you dont have one) the symbol is the letter or two in the middle of each square. For example, the symbol for Hydrogen is "H", the symbol for Potassium is "K", the symbol for neon is "Ne" & The symbol for Carbon is "C". The symbol is always one or two letters, except for the last few elements, which for now have 3, until they get real names.
