  25. Hydrogen is so light and diffusive that it can escape the atmosphere when it is uncombined.
  26. Hydrogen is the only element who’s isotopes have been given different names (Deuterium [1 neutron], Tritium [2 neutrons].
  27. Creates a flame of bright yellow when ignited.
  28. Reacts easily with oxygen to form water (H2O).
  29. Obtained from mines, oil, and gas wells

Uses

  1. When hydrogen is combined with liquid oxygen it creates rocket fuel
  2. Hydrogen is combined with nitrogen to produce ammonia
  3. Here are some compounds with hydrogen: Hydrogen Fluoride (HF), Hydrogen Chloride (HCl), Hydrogen Bromide (HBr), Hydrogen Iodide (HI), water (H2O), Hydrogen Sulphide (H2S), ammonia (NH3), methane (CH4), table sugar (C12H22O11), and Hydrogen Peroxide (H2O2).
  4. Used for filling balloons.
  5. Used in the process of metal refining.
  6. Not used for zeppelins anymore after the great disaster of the Hindenburg crash.
  7. For making fuel cells.
  8. Tritium (3 neutrons) is used in the production of the hydrogen fusion bomb, making luminous paints, and used as a Tracer.
  9. For making ethanol.
  10. The stars, like the Sun, burn hydrogen to produce energy (the Sun has enough hydrogen left for another 5 billion years).
  11. The production of hydrogen in the U.S. is 3 billion cubic ft. per year.
  12. Used in: hydroealkylation, hydrocracking, and hydrodesulfurization.

 

 

 

History

  1. Comes from the Greek hydro & genes meaning water generator
  2. Hydrogen was isolated and identified as an element by Henry Cavendish in London, England in 1766
  3. All elements originally came from hydrogen because it is the simplest and lightest element.
  4. Not used for zeppelins anymore after the great disaster of the Hindenburg crash.

Glossary

Hydro: Water (in Greek)
Isolated: Identify (something) and examineor deal with it seperately.
Fusion: The process or result of joining two or more things together to form a single entity.
Refining: Remove impurities or unwanted elements from (a substance).
hydroealkylation: A petroleum refining operation in which heat and pressure are used to remove methyl groups or larger alkyl groups from hydrocarbons, or to change positions of these groups on the molecule; used to upgrade low-value products.
Isotopes: One of two or more atoms having the same atomic number but different mass numbers.
Hydrocracking: A process by which the hydrocarbon molecules of petroleum are broken into simpler molecules, as of gasoline or kerosene, by the addition of hydrogen under high pressure and in the presence of a catalyst.
Hydrodesulfurization: A catalytic process in which the petroleum feedstock is reacted with hydrogen to reduce the sulfur content in the oil.
Diatomic: Made up of two atoms.
