The Rutherford Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus

Atomic energy By: Hiram A. Murray III Background info The origin of the phrase atomic energy check in from the years of 1905-10. It is defined as energy released by reactions within atomic nuclei‚ as in nuclear fission or fusion. Now a days it is referred to Nuclear energy. Nuclear power uses fission (splitting atom nuclei) to produce energy. Atom nuclei is also none as the nucleus (center of the atom). Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear

the Atomic Mass # differ from the Atomic #? The atomic mass differs from the atomic number by the fact that the atomic mass is composed of the total number of protons and neutrons in the nucleus‚ and the atomic number is the number of protons found in the nucleus‚ and is identical to the charge of the atom. 3) What is an isotope? Give an example (show how it is an isotope). An isotope is a form of the same atom that differs from the original atom in atomic mass

Atomic weapons are similar to poison gas – both are barbaric.The U.S.A. should not shock the world with such a weapon.
