Matter Wave and de Broglie's Atomic Model. Light has both particle and wave properties at the same time. Likewise, de Broglie France, - thought that such In , Niels Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. Part 1: Read the following information on elements, compounds and mixtures. Fill in the blanks where necessary. An element is always uniform all the way through homogeneous. These properties of the three states of matter are easily observed. They are explained, however, by a theory that describes the behavior of particles far too small to be seen.

It stated that a sample of a pure compound always contain the same elements in the same proportion. And also that the samples are always the same regardless of where or how they were formed. His theory stated that matter is composed of different weight atoms and combine in simple ratios by weight. Dalton's atomic theory is based on the following postulates: 1. All matter consists of tiny particles 2. Atoms are indestructible and unchangeable 3. Elements are characterized by the mass of there atoms 4. When Elements react, their atoms combine in simple, whole-number ratios Jan 1, The civil war began in when Confederate troops bombarded Fort Sumter. It took 2 years 2 months and 5 days to complete it. Jan 1, J. J Thomson Discovers Electron Thomson discovered the electron in From the discovery of the X-ray, Thomson deduced that cathode rays showed a single charge-to-mass ratio e m and must be composed of a single type of negatively charged particle, which he called "corpuscles," but Johnstone Stoney had proposed the term electron earlier in electrochemistry.

Thomson aslso realized that it was also a subatomic particle, the first one to be discovered. Thomson also discovered the isotope. The Planck constant can be used to find the energy of a proton. Jan 1, Henir Becquerel Discovers Radioactivity Becquerel discovered that uranium spontaneously emits radiation. He placed a sample of uranium and black paper in a paper bag and upon mistake discovered days latter the black paper had been exposed to radiation. The mater is positively chargered which is the "pudding" and the electrons, which are negatively charged, are the "plums. The chage of an electron can be used to calculate mass. Jan 1, Ernest Rutherford Split an Atom Rutherford was the first to split an atom and consequently discovered that uranium could be used to tell the age of things. By using the decay rate of uranium and telling how much of it was left in the sample the relative age could be told. Rutherford also was the first to propose the idea of Alpa and Beta rays come off radioactive materials.

However one of his most noted acomplishments was the discovery of the nucleus and proposal of the Nuclear Model. Jan 1, Rutherford's Model Rutherford's model was created in and it consisted of a small positively charged nucleus in the middle and electrons round it. It includes shells that show electrons orbits. Bohr postulated that electrons orbit around the atom's nucleus in He also explained how electrons emit or absorb energy. Jan 1, The quantum model got ride of Bohr's orbital paths and replaced tham with waves. Jan 1, Erwin Schrodinger In Eriwn Schrodinger produced the wave equation that is now known as the Schrodinger equation. Erwin Schrodinger took the ideas developed by de Broglie, Heisenberg and others and put them together in one equation. When solved the equation can predict the properties and reactivities of all atoms and molecules. Jan 1, Louis de Broglie and Waves De Broglie stated the idea that both light and matter had waves.

He also was the first to propose that electrons were only allowed certain orbits or that there were electron waves. This solved the jigsaw puzzle of the atom. This lead to the ldiscovery of nuclear fission and eventual lead to development of nuclear weapons and nuclear power production. Kennedy was assasinated in Dallas Texas.

He believed that the atom was a uniform sphere with a positive charge and had electrons embedded in it.
