John Dalton was born on September 6th 1776 in England. Dalton became intrested in atoms and such because he was previously involved in the study of meteorology. The day and date of his birth as his family never recorded it properly in the family bible (the way it was done in those days) so nobody for sure knows his real birthday but its believed to be on September 6th. Dalton had Four Atomic Theories in which his model was based on.They were chemical elements are made of atoms, the atoms of an element are identical in their masses, atoms of different elements have different masses, atoms only combine in small, whole number ratios such as 1:1, 1:2, 2:3, and finally atoms can be neither created nor destroyed. After Dalton laid the foundation for the atom other scientists picked up where he left off. The next guy to pick off was a man named J.J. Thompson, Thompson was the man who discovered an electron. Thomson discovered the electron in a series of experiments designed to study the nature of electric discharge in a high-vacuum cathode-ray tube. In 1904 he suggested a model of the atom as a sphere of positive matter in which electrons are positioned by electrostatic forces. Here his techniques led to the development of the mass spectroscope, an instrument perfected by his assistant, Francis Aston for which Aston received the Nobel Prize in 1922.Thomson built a cathode ray tube ending in a pair of cylinders with slits in them, These slits were connected to an electrometer a device for measuring electrical charge. Thomson found out if the rays were magnetically bent so that they could not enter the slit, the electrometer registered little charge, which meant that the negative charge was inseparable from the rays. The first cathode ray tube scanning device was invented by the German scientist Karl Ferdinand Braun in 1897. Braun introduced a cathode ray tube with a fluorescent screen, known as the cathode ray oscilloscope. The screen would emit a visible light when...
