Hydrogen

Hydrogen is the lightest and most common element in the universe. It was formed shortly after the Big Bang and is mainly found in stars, water, and living things. Hydrogen is used as a clean fuel source, in rockets, and to produce electricity. On the periodic table, hydrogen’s cell shows it has an atomic number of 1, meaning it has one proton, and its properties explain why it is very reactive.
