What is hydrogen known for?
Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. Hydrogen is the raw fuel that most stars ‘burn’ to produce energy. The same process, known as fusion, is being studied as a possible power source for use on earth.
Do we experience hydrogen in our everyday life?
Hydrogen gas breaks down petroleum products. Hydrogen is used to create the ammonium found in fertilizer. Hydrogen is used to prepare all kinds of foods and fats. Hydrogen is also used to make methyl alcohol, which is found in paints, varnishes, inks, cements and paint strippers.
Is hydrogen important to a human body?
The most important function of hydrogen in the human body is to keep you hydrated. Water is made up of hydrogen and oxygen and is absorbed by the cells of the body. Therefore, it is a crucial element which is used not in our body but also as a fuel, in military weapons etc.
