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 gas is two hydrogen atoms bonded together, H2. Oxygen gas is two oxygen atoms bonded together, O2. Water, is one oxygen atom bonded to two different hydrogen atoms, H2O. When atoms are bonded together, (H2, O2, H2O etc.) we call the total structure a molecule. Hydrogen atoms and oxygen atoms are found in many different molecules, and these different molecules make up, solids, liquids, and gasses. Whether a material is a solid, liquid, or gas depends on how these molecules (made up of atoms) interact with each other.
