Earnshaw in Chemistry of the Elements, 2nd edition, Butterworth, UK, 1997. Budavari (Ed.) in The Merck Index, 11th ed., Merck, USA, 1989. Keiter in Inorganic Chemistry : Principles of Structure and Reactivity, 4th edition, HarperCollins, New York, USA, 1993. Interactive periodic table with up-to-date element property data collected from authoritative sources. In principle, it can asphyxiate through denying the body access to oxygen. Hydrogen gas is not toxic but is dangerous if mixed with air or oxygen because of the fire and explosion risk. Hazards and risks associated with hydrogen: Image showing periodicity of the logarithm of the abundance of the chemical elements as a cityscape on a periodic table grid. Image showing periodicity of the logarithm of the abundance of the chemical elements as a heat map on a periodic table grid. Calculate how much hydrogen is in your body Enter your weight here: Hydrogen is the most abundant element in the universe, and as its atomic number suggests, its pretty important. You must enter a number, not text! Elements for which there are no data will always give a value of zero for the weight, no matter what you put in the weight box. Enter your weight in either kilograms or pounds and click the "Calculate" button. Choose a clickable element in the table below to learn more about it and its role in energy and society. : PROLEE The Periodic Table with Real Elements Large Size 8L x 5 H, Table of Elements with 360 Degree Rotating Wood Stand, Periodic Table. You can use this form to calculate how much hydrogen your body contains. How much hydrogen is in your body? Find out here. Visualize trends, 3D orbitals, isotopes, and mix compounds. Elements with similar properties formed a suit that he placed in columns ordered by ascending atomic weight. Fond of card games, he wrote the weight for each element on a separate index card and sorted them like in solitaire. Human abundance by atoms: 620000000 atoms relative to C = 1000000 Interactive periodic table showing names, electrons, and oxidation states. Dmitri Mendeleev is best known for creating the periodic table. Human abundance by weight: 100000000 ppb by weight.The abundances of the elements in humans. Some bacteria are known to metabolise molecular hydrogen (H 2). A form of water in which both hydrogen atoms are replaced by deuterium ( 2H, or D) is called "heavy water" (D 2O) and is toxic to mammals. Hydrogen is present in all organic compounds. Hydrogen makes up two of the three atoms in water and water is absolutely essential to life.
