    most common thing in our life - WATER. Water consists of two chemical elements, hydrogen and oxygen. Each molecule of water consists of two hydrogen (H2) atoms and one oxygen (O) atom. Chemical binding between these three atoms is very stable and strong. Therefore, the reaction of hydrogen and oxygen is under normal circumstances very intense and generates a lot of energy. 2H2 + O2 ® 2H2O + energy Both, hydrogen and oxygen are gases at normal temperatures and pressures and the product of this

    Hydrogen is a diatomic element that is in a gaseous form at room temperature. Its most identifying characteristic is the fact that it is highly explosive. It is the lightest element in the world, and has a lifting power of 8% more than that of helium. Hydrogen was used in airships and zeppelins for more than 20 years during the beginning of the 20th century. This practice stopped abruptly after the German airship Hindenburg disaster over New Jersey. It is used in fuel cells to create electricity

    HYDROGEN Hydrogen is a gaseous element, symbol H, usually classed in group 1 (or Ia) of the periodic table Hydrogen melts at –259.2° C (–434.56° F) and boils at –252.77° C (–422.986° F). Hydrogen was confused with other gases until the British chemist Henry Cavendish demonstrated in 1766 that it was evolved by the action of sulfuric acid on metals and also showed at a later date that it was an independent substance that combined with oxygen to form water. The British chemist Joseph Priestley named

  • The History and Production of Hydrogen

    1175 Words  | 3 Pages

    Hydrogen gas was first identified as an element in 1766, by British scientist Henry Cavendish, in an experiment wherein he separated hydrogen gas by reacting zinc metal plates with hydrochloric acid. Cavendish found that when he applied a spark to the resulting hydrogen gas, it yielded water. It wasn’t until some years later that French chemist Antoine Lavoisier gave hydrogen its modern name. The word hydrogen is derived from the Greek words ‘hydro’ and ‘genes’, which translate as ‘born of water

    on the periodic table. One of the elements is hydrogen. Hydrogen the first element in the periodic table it is colorless, combustible and lightest of all gases. It was first artificially produced in the early 16th century by Henry Cavendish. As we know hydrogen can be used as fuel, and the fossil fuel energy has been used in many areas, but human can’t produce the fossil energy fuel by themselves, the more we use, the less we have left, so hydrogen may be used as the most common use fuel instead

  • Metallic Hydrogen

    Hydrogen: the most abundant element in the universe. Normally it has been considered to remain a non-metal at any range of temperatures and pressures. That is, until now. Recently this year, hydrogen was changed into a metallic substance, which could conduct electricity. An experiment conducted by William J. Nellis et al. at the Lawrence Livermore National Laboratory accomplished this feat. Hydrogen was converted from a non-metallic liquid, into a liquid metal. The likelihood that the most abundant

  • The Hydrogen Bomb

    The Hydrogen Bomb Thesis Statement The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb, which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT. The Hydrogen Bomb The Atomic Bomb Was A Essential

    containing more than about 8 percent hydrogen peroxide are corrosive to the skin. First recognized as a chemical compound in 1818, hydrogen peroxide is the simplest member of the class of s. Of the several processes of manufacture, the principal ones involve reactions of oxygen from the air with certain organic compounds, especially anthraquinone or isopropyl alcohol. Major commercial grades are aqueous solutions containing 35, 50, 70, or 90 percent hydrogen peroxide and small amounts of stabilizers

    essential element is hydrogen, the first element on the period table (located under Group 1 as an alkaline metal) is composed of a single proton and electron; therefore having an atomic number and atomic mass of 1 and electron configuration of 1s1. In fact, hydrogen is the lightest, simplest and most commonly found chemical element in the universe (it makes up about 90% of the universe by weight). Interestingly enough, the heavier elements on the periodic table were either made from hydrogen or other elements

    Hydrogen sulphide has a boiling point of -82 degrees Celsius and a melting point of -60 degrees Celsius. There are 2 hydrogen and 1 sulphide molecule. Simple molecule’s which are covalent have lower melting and boiling points as they do not need too much energy to separate the bonds because they are as polarised as water. In hydrogen sulphide the intermolecular forces are known as Dipole-Dipole forces which are less powerful than hydrogen bonding which is in water therefore water has the strongest
