Chemical Symbols and Formulas Chapter 6

Elements In 1817, Jakob Berzelius created an international system to represent all elements with symbols. We still use his system today (all over the world), which involves elements being represented by one or two letters found in their name. The first letter is always capitalized. If there is a second letter, it is always a small letter.

CHEMICAL SYMBOLS Different countries may have different words or spellings for elements, but everyone uses the same symbols. You can probably see why carbon has the symbol C and nitrogen has the symbol N, but why does sodium have the symbol Na?
