Element name : Hydrogen. Atomic symbol : H. Atomic number : 1. Atomic mass : 1.00794. Standard state of matter is gas at 298k. Density : 0.0899.
Out of all the elements, Hydrogen is the lightest and simplest. It is by far the most abundant element in the world and makes up about 90% of the universe by weight. It burns in air to form only water as a waste product. On the element chart, it will be found in a yellow square. It's an colorless, odorless gaseous element, It got its name from the Greek words, hydro and genes which put together mean water forming. Hydrogen is also added to fats and oils through a process called Hydrogenation. Hydrogen has three common isotopes. The first is called protium, the second is deuterium, and lastly, the third is called tritium. Like electricity, Hydrogen is an energy carrier. The fuel cells are very efficient, but expensive to build, it must be produced from another substance. Hydrogen is not widely used, but it will most likely be a popular energy carrier in the future. Most of the Hydrogen that is currently used in the United States is used by industry for refining, dealing with metals, and processing foods. Today, there are more than 300 Hydrogen- fueled vehicles in our country. Most of these vehicles are buses and automobiles powered by electric motors and they produce almost no pollution. But, Hydrogen is also used for many other things such as the reduction of oxide ores, the refining of petroleum, in the synthesis of ammonia, and much more. Chemically, Hydrogen reacts with most of the elements. Also, tons of compounds contain Hydrogen, the list could go on and on. Some examples are gasoline, cleaning products, synthetic clothing, cotton, plastic, paint, rubber, etc.
History of Hydrogen 1671; Boyle published paper pertaining to "flammable air" that is created when metals were exposed to acids. 1766; Hydrogen was isolated and studied by Henry Cavendish. 1780's - Antoine Lavoisier split water molecules into hydrogen and oxygen, and recombined the them to make water again. 1839 - Sir William Grove develops the first fuel cell, by reversing the process of electrolysis 1937 - Hindenburg, which was filled with hydrogen, burns while landing. 1960's - Fuel cells provide electrical power for Gemini and Apollo space programs. 1980's - Automotive companies began testing fuel cell technology for cars. 1999 - First production hybrid electric vehicles (HEV), the Honda Insight and Toyota Prius, become available in the United States. 2003 - Honda releases first production fuel cell car for Los Angeles.
