One common chemistry assignment is to name or even memorize the first 20 elements and their symbols. The elements are ordered in the periodic table according to increasing atomic number. This is also the number of protons in each atom. These are the first 20 elements, listed in order: H - Hydrogen He - Helium Li - Lithium Be - Beryllium B - Boron C - Carbon N - Nitrogen O - Oxygen F - Fluorine Ne - Neon Na - Sodium Mg - Magnesium Al - Aluminum Si - Silicon P - Phosphorus S - Sulfur Cl - Chlorine Ar - Argon K - Potassium Ca - Calcium Element Symbols and Numbers The number of the element is its atomic number, which is the number of protons in each atom of that element.
