Let's start our tour of the periodic table with hydrogen. Why start with hydrogen? Hydrogen is the first element in the periodic table and the most basic and common of all elements in the universe. Over ninety percent of all the atoms in the universe are hydrogen atoms and they are the lightest of all elements. Although it has been around forever, it took a chemist named Lavoisier to name it. The name hydrogen comes from the Latin word "hydro" which means water. Lavoisier knew that hydrogen was in all water molecules. Scientists use the letter "H" to represent hydrogen in all chemical equations and descriptions.
