History of the Atom

John Dalton

Democritus
 * John Dalton was born on Sept. 6th, 1766 in Eaglesfield, Cumberland, England. He died on July 27th, 1844.
 * He was a chemist and physicist. John created the "Atomic Theory." He made his theory by his fascination of weather and the atmosphere which his research led to his nature of gases. []

His atomic ideas had no effect on other Greek philosophers. []
 * Democritus was born in 460 B.C. in Abdera, Thrace. He died in 370 B.C.
 * Supposedly he was the greatest Greek physical philosopher. He postulated the existence of tiny, little particles that make up all things which he called "atoms."

Breakthrough Discovery Experimental

[] Laser []
 * IBM did an experiment on individual atoms on high speed. They experimented the atoms at a speed of one million times faster than previously possible. For over two decades the IBM researchers have been using the Scanning Tunneling Microscope to understand the fundamental properties of matter at the atomic scale. Its remarkable that you can measure nanosecond-fast phenomenon. They added the dimension of time.
 * Scientists from both the U.S. and Austria found a way to move particles from an atom with a laser light. Experts said if you do the same with massive particles, could lead to new super fast computers. When physicists talk about "teleportation" they're talking about the "quantum states" between separate atoms. That would refer to the atom's motion, energy, magnetic field, and other physical properties. Computers in the future would have the information that forms qubits.

Atomic Structures


 * The different parts of an atom are protons, neutrons, electrons and the atomic nucleus.
 * Different particles that make up the atom are protons, neutrons and electrons.
 * The protons and neutrons are located in the atomic nucleus. Electrons are found floating in the region around the nucleus. http://www.buzzle.com/articles/parts-of-an-atom.html
 * Element atoms have a different number of protons, neutrons and electrons which they have different atomic numbers and properties. http://answers.yahoo.com/question/index?qid=20080928161631AATiaLw
