Dalton`s Atomic Theory
Daltons atomic theory states each chemical element has atoms that vary in size and shape. -
daltons atomic model
Dalton’s atomic model is one of the fundamentals of physics and chemistry. This theory of atomic composition was made by John Dalton. Dalton came with his Atomic theory as a result of his research into gases. He discovered that certain gases only could be combined in certain proportions even if two different compounds shared the same common element or group of elements. -
JJ Thomson's Two-Slit Experiment
Two-Slit Experiment: Monochromatic light incident on a pair of slits gives interference fringes, alternate light and dark bands, on a screen variation in the intensity of the light at the screen when both slits are open. With a single slit, there is no interference pattern; the intensity variation is shown by the broken line. As would give the variation in the intensity of electrons. -
JJ Thomson's Atomic Theory
Discovered the Electron: Revolutionized the knowledge of atomic structure by his discovery of the electron. The major shortcoming addressed of JJ Thomson’s model is that it doesn’t explain how positively charged particles are shielded from negatively charged particles, without getting neutralized. -
Rutherford
1910-11 Rutherford discover the nucleus of an atom many people didn'tthink it was that important till Bohr showed it was -
Ernest Rutherford
Rutherford over turned thomson's model showing that an atom has a tiny massive nucleus -
Gold Foiled experiment
shot particles through a gold foil and the atoms that bounced back were the ones hitting the nucles which led Rutherford to find the nucleus -
Neils Model
A Bohr model of the hydrogen atom, showing an electron jumping between fixed orbits and emitting a photon of energy with a specific frequency. -
Change
Neils passed on to a study of the structure of atoms on the basis of Rutherford's discovery of the atomic nucleus. By introducing conceptions borrowed from the Quantum Theory as established by Planck,
