This model explained the description of an inner structure of the atom theoretically. It was strongly supported by Sir Joseph Thomson, who had discovered the electron earlier. During cathode ray tube experiment, a negatively charged particle was discovered by J.J. Thomson. Thomson Atomic Theory . Thomson's discovery of the electron completely changed the way people viewed atoms. Up until the end of the 19th century, atoms were thought to be tiny solid spheres.

He was an English physicist and Nobel laureate in physics, he was known for the discovery and identification of the elect, and with for discovery of the first subatomic particle. For Thomson’s atomic theory model he was awarded noble prize in 1906. 12. • J.J. Thomson died on August 30, 1940 Click Here To go to Outline 13. Click HereTo go toOutline 14. • MLA style: "J.J.

Cathode ray tube experiment A cathode ray is simply a glass tube where the majority of the air within the tube has been vacuumed out with electrodes at either side which was conducted by an electric charge that caused the tube glow. Thomson thought of this "plum pudding" idea after he discovered the electron, before that he believed it was just a small sphere. Dalton's atomic model Dalton's model explained that atoms were tiny invisibly, indestructable particles; And that each had a certain mass, size, and chemical behavior that determined by what kind of element they were. Dalton’s atomic theory provides a microscopic explanation of the many macroscopic properties of matter that you’ve learned about. For example, if an element such as copper consists of only one kind of atom, then it cannot be broken down into simpler substances, … JJ Thomson atomic theory Thomson Enrico contributed to the atomic theory because he found a way to split the atom, which contributed to the atomic bomb which is commonly used in nuclear power plants to this day.

Dalton's atomic model Dalton's model explained that atoms were tiny invisibly, indestructable particles; And that each had a certain mass, size, and chemical behavior that determined by what kind of element they were. Millikan and Thomson's Contributions to the Atomic Theory Theory Inferences From his experiments, Thomson discovered that cathode rays were 1000 times lighter than hydrogen atoms, and that the rays were always the same mass regardless of what atom it came from. Atomic theory was now accepted by the scientific community, but the next advancement was through the discovery by J. J. Thomson’s in the year 1897. He defined in his theory that the atoms as uniformly packed spheres of positive charges matter filled with the negatively charged electron.
