Hydrogen Symbol: H 1 Atomic No.: Atomic Mass: 1.0794 Electron Valence Drawing: Proton Nucleus Neutron 1P 0N Valence Shell Electron Configuration: 1s 1 Is this element a metal, metalloid, or non-metal? Non-Metal What is the importance of this element to food or nutrition? • • • Hydrogen peroxide (H2O2) is used as a microbial control agent in fresh produce and as a disinfectant in food packaging such as juice boxes. Hydrogen is found in all of the carbohydrates, proteins, and fats that make up the food we eat and provide the energy and building blocks for our body’s metabolism. Water(H20) is needed for our body to function and is very important in determining the properties of the food we eat.
