The Hydrogen Bomb

Hydrogen bomb is a weapon deriving a large portion of its energy from the nuclear fusion of the hydrogen isotopes. The hydrogen bombs functions by the fusion or joining together, of lighter elements into heavier elements. The hydrogen bomb is also known as the thermonuclear bomb because extremely high temperatures are required in order to initiate the fusion reactions. The presumable structure of a thermonuclear bomb is this:atomic bomb in the center, around it is a layer of thin lithium deuteride, around that is another thicker outer layer that holds it all together to make a larger explosion. The first thermonuclear bomb was exploded in 1952 at Eniwetok by the U.S. and the second in 1953 by the USSR. France, Great Britain, China , and India have also exploded the bomb. Hydrogen was formerly used for filling up balloons, airships, and other lighter than air crafts. It is not used a lot now because it can cause fire if not used safely. Now helium is used to fill up ballons and crafts.Hydrogen is now used in the Haber process for the fixation of atmospheric nitrogen, in the production of methanol and in hydronenation of fats and oil. Hydrogen was prepared many years earler but was first recognized as a substance for flammable gas in 1766 by Henry Cavendish.
