Greatest Discoveries in Chemistry

* The elements are not fire, air, water, and earth.

* From Priestly discovered oxygen, but Fwasia developed the elements. It all came from the discovery of oxygen.

* Oxygen, carbon, and hydrogen. Dolton hypothesized that hey were made up of atoms. Ultimate particles, then become atomic weights. Atomic theory.

* Joseph Gay Lusak. Gases made of multiple atoms (molecules), not a single atom.

*Synthesis of ureas. Fredick Volure, had placed two inorganic materials and combined it made crystals that looked like organic materials found urine. These crystals were the same as the urine, he had made urea out of inorganic materials.

*Chemical Structure. Sodium and Chlorine combined with fixed ratios. Kekula used the symbols for chemicals then added lines to see how it bound to other materials. Benzen did not fit his formula. The six carbon atoms in Benzen formed a ring, he discovered this when he dreamt of a snake eating its own tail (which is called orbus, by the wayt, not hta thas anything to do with science). Carbon combined with other molecules was discovered with this revelation of Benzen's ring.

* Periodic table disovered by Mendelia. He could also predict the spaces of three undiscovered elements like Borum and other such elements.

* Electrochemistry

* Prism + telescope = spectroscope to see the spectrum of an element + fire. Cesium, Rubidium was found this way. Sunlight had two lines were the same as with sodium, finding that sun had sodium.

* Joseph Thompson = electron. Cathorays exposed to a magnet, it bend. IT showed that it had electro charged matter because magnet only effects matter. Subparticle matter was discovered.

* Gilbert Luis developed model of the atom. Shells had electrons that circled the atom. Weh Sodium gave up an electron from out shell and cholirde accepted it, the two combined and sodium chloride was made.

* Radiation. Henry bekrell. Uranium to see if radiation. Marie Curier picked up the research of radioactivity. Pulonium and radium were found from this. Radium was determined to be 1,000,000x's more radioactive than uranium. She found that radioactivity was more atomic than chemical.

* Alpha and beta particles and gamma rays were found by Rutherford.

* Plastics. cellulous can be manipulated to create plastic. Plastics = plymere = long chain molecules.

* Buckey-balls. Fullorines. Won't accept anymore atoms. Key number was 60. Most symmetry than any other molecule. Pure carbon = carbon nanotubes (buckey-tubes). The tube is the stiffest material in the world.
