History of the atom Dalton John Dalton was a chemist who was famous for his atomic theory. He discovered that air was a mixture, not a compound. He also discovered that the solubility of a gas depends on the weight of its atoms. He published the law of partial pressures, known as D Thomson Sir Joseph John Thomson was a British physicist who won the 1906 Nobel Prize for physics for his research on the conduction of electricity by gases. He used a discharge tube to identify an electron. He was the first to record this information. The way he Rutherford Ernest Rutherford was a New Zealand scientist. Many of our current views of matter come from him. He was the first to do the gold foil experiment. He also developed his own structure of the atom in 1911. The nucleus was positive and the empty space arou Bohr Niels Bohr picked up where he thought Rutherford left off. He used much of the previously discovered information to develop some assumptions. The first was: Electrons can only move in a certain number of energy levels. This would mean that they had a lim Current structure of the atom It is now known that atoms have wave patterns. The Stanford Center discovered that protons as well as neutrons are actually made up of quarks. Rutherford?s model was found to be reasonably accurate. Radio Activity Alpha, beta and gamma rays are radio waves in small proportion, and they are used in X-rays. The radiation produced sends off a very short wave length and are different for each type of ray. X-rays were discovered by a man named Roentgen in 1895 by con Nuclear Reactions Alpha, beta and gamma are used to describe the decay process involved with nuclear reactions. This process was developed also by Ernist Rutherford and is used in modern science today. The time taken for half of the original number of atoms to decay is c Fission and Fusion Nuclear Fission Nuclear fission is an action that releases energy. The energy from the fission generates electric power, used to sustain our civilization. Atoms are split by using neutron which collide with the atoms. The result are 2 to 3 fragments with a mass less Nuclear Fusion Nuclear fusion occurs when two lighter elements are combined to form a new, larger element. During the combining process great amounts of energy are released. In the cases where the elements nuclei contains a low atomic weight the separation of a neutr he promise of such a clean and vast supply of energy are incentives for further research. The energy released could produce enough power for many generations to come. General Applications Radiation is used in many different areas within society, anywhere from medicine to atom bombs.
