Exclusively as oxygen is important for us, "Hydrogen" is also important for us. The byproduct of a hydrogen and oxygen explosion is water or (H2 O). , which is very important for this earth. Hydrogen is very flammable and burns with an invisible flame. It burns when it comes into contact with oxygen. Hydrogen is the first element in the periodic table. It is the simplest possible atom made of a proton in the nucleus orbiting a single electron. Hydrogen is the lightest of the elements and the most abundant element in the universe. Hydrogen is a very useful element. It is used to make ammonia for fertilizers, refining metals, and methanol for making artificial material like plastics.
