Both oxygen and hydrogen are reactive, colorless gases that are found in the air and are essential for your survival. The primary difference between the two elements is their physical and chemical properties.
Hydrogen occurs as a gas that you canât see and canât smell. It is about 14 times lighter than air. When you combine two atoms of hydrogen with one atom of oxygen you get a water molecule H 2O. Like nitrogen, hydrogen can also be condensed to a liquid that freezes at â 259Â°C (-434Â°F) and boils at -252Â°C (-423Â°F). Hydrogen is one of the most common elements in our universe. The sun and many stars are made of hydrogen.
