Why is hydrogen named hydrogen? He is usually given credit for its discovery as an element.In 1783, Antoine Lavoisier gave the element the name hydrogen (from the Greek hydro meaning water and genes meaning creator)when he and Laplace reproduced Cavendish's finding that water is produced when hydrogen is burned.

What Is Urea Nitrate? Hydrogen is a chemical element with symbol H and atomic number 1. With a standard atomic weight of circa 7000100800000000000♠1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state.

Forms of Hydrogen What is Hydrogen? Hydrogen gas has been shown to have a therapeutic effect on over 150 human diseases, 1 but what is Hydrogen? Hydrogen is the lightest and simplest element with the symbol H. It consists of only one electron and one proton and, under normal conditions, it exists primarily in its diatomic form as molecular hydrogen (H 2 gas). It is what powers the sun by fusion to produce helium.

Hindenburg & Hydrogen The disaster was blamed on the extreme flammability of the hydrogen lifting gas that filled most of the airship. This bad reputation of hydrogen still bothers car manufacturers today, as they explore the use of hydrogen as a safe, non-polluting alternative to fossil fuels for powering cars.

New elements on the periodic table are named Until now, they'd been known by the Latin words for their atomic numbers: ununtrium, ununpentium, ununseptium and ununoctium. Elements can be named for a mythological concept or character, a mineral or similar substance, a place or geographical region, a property of the element, or a scientist. And, of course, they must end in -ium, -ine or -on depending on the grouping of elements they belong to.

- Hydrogen has three isotopes (triplets): hydrogen-1 (protium), hydrogen-2 (deuterium) and hydrogen-3 (tritium). In the illustration below, we can see subscripts and superscripts. The superscripts 1, 2 and 3 written before H are the atomic masses of the isotopes of hydrogen and the subscript 1 is the atomic number.

The Three Isotopes of Hydrogen Protium is also called hydrogen-1 (the number after the dash is the atomic mass). The same goes for the other two isotopes of hydrogen. The three isotopes of hydrogen are illustrated below: Besides the number of neutrons and the atomic number, these isotopes of hydrogen also differ in terms of their natural abundance.

CONTENTS The ordinary isotope of hydrogen, H, is known as Protium, the other two isotopes are Deuterium (a proton and a neutron) and Tritium (a protron and two neutrons). Hydrogen is the only element whose isotopes have been given different names. Deuterium and Tritium are both used as fuel in nuclear fusion reactors.

Neon Neon was the second of these three rare gases to be discovered, and was immediately recognized as a new element from its bright red emission spectrum. The name neon is derived from the Greek word, νέον, neuter singular form of νέος [ neos ], meaning new. Neon is chemically inert and forms no uncharged chemical compounds. During cosmic nucleogenesis of the elements, large amounts of neon are built up from the alpha-capture fusion process in stars.

How to Name a Hydrocarbon Chain Using the IUPAC Method Hydrocarbons, or compounds based on a chain of hydrogen and carbon, are the basis of organic chemistry. You need to learn to name them according to the IUPAC, or International Union of Pure and Applied Chemistry, which is the currently accepted method for naming hydrocarbon chains.

Deuterium Facts Hydrogen is unique in that it has three isotopes which are named. Deuterium is one of the isotopes of hydrogen. It has one proton and one neutron. The most common isotope of hydrogen is protium, which has one proton and no neutrons.Because deuterium contains a neutron, it is more massive or heavier than protium, so it is sometimes called heavy hydrogen.By Anne Marie Helmenstine, Ph.D. Deuterium is a stable isotope of hydrogen. 2  The natural abundance of deuterium in the ocean is approximately 156.25 ppm, which is one atom in 6,400 of hydrogen. 3  The name for deuterium comes from the Greek word deuteros, which means second.

Hydrogen: historical information The symbol used by Dalton for hydrogen is shown below. [See History of Chemistry, Sir Edward Thorpe, volume 1, Watts & Co, London, 1914.] In 1839 a British scientist Sir William Robert Grove carried out experiments on electrolysis. He used electricity to split water into hydrogen and oxygen.
