Transcript of The History of Chemistry

The History
of
Chemistry Chemistry started in the Fertile Cresent around 3,000 B.C. as the art of making perfume, practiced by women. By 1000 B.C., Egyptians used Chemistry for making medicine, dyes, and other useful things. Greeks and Egyptians believed that adding a substance called Xerion to valueless metals would turn them to gold (which was not true.) These beliefs continued through the Middle Ages. Some people think that Muslims discovered the science of Chemistry, but it actually was discovered in all different parts of the world in different ways for different purposes. Chemistry started early, but huge discoveries were not made until later in time. In 1767, Joseph Priestley discovered oxygen and a few other important gasses. A.L. Lavoisier discovered nitrogen and organic compounds in the 1700's and is reffered to as the "Father of Chemistry." as history progresses, more Chemists made discoveries of the
elements One of the most important discoveries was of the Periodic Table of Elements by Dmitri Mendeleev. He left spaces for new elements to be discovered. by Savvy Lankford Another great discovery was made by John Dalton in 1803 and it states that everything is made of atoms, extremely small pieces of matter. After that, the discoveries only got more interesting. Wilham Roentgen discovered x-rays in 1895. This was followed by the discovery of electrons, radioactive elements... neutrons, and nuclear power. Chemistry is now used industrially;
time has improved the methods and
efficency of glass, crystal, tile, plaster,
and glaze making. New instruments were developed such as Bunson burners, scales, weights, and many others, http://www.byui.edu/societies/chemistry/bylaws.htm http://www.vaughns-1-pagers.com/biology/human-periodic-elements.htm http://www.public.iastate.edu/~cfford/342worldhistoryearly.html http://www.utilitarianism.com/joseph-priestley.html http://adamant.typepad.com/seitz/2007/10/index.html and new discoveries are made everyday!
