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

INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

My topic is the atomic bomb. Two questions I have are one‚ why did the atomic bomb happen? Two‚ how did the atomic bomb change the world? The sub-topics introduce the Manhattan project. Japan refused to surrender‚ why the United States dropped an atomic bomb on Hiroshima and Nagasaki? The atomic bomb was first used in warfare at Hiroshima and Nagasaki in august 1945‚ and the bomb played a key role in ending World War II. The Atomic bomb created the Manhattan project. The Manhattan

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

The Atomic Bomb: Beneficial or Disastrous? Was dropping the atomic bomb on Hiroshima and Nagasaki at the end of World War II the most affective action that the United States could have taken? In the American eyes it was a good punishment on Japan in response to the Pearl Harbor attacks on December 7‚ 1941. The way the Japanese leaders launched the fighter planes that came in a destroyed many U.S. naval ships and took thousands lives‚ including soldiers and innocent bystanders‚ was a completely immoral

The End of World War II The United States Decision to drop the Atomic bomb has been a controversial topic since the day the first bomb was dropped August 6‚ 1945. President Harry Truman made the ultimate decision to use the atomic bomb‚ to him it was a clear decision that this would end the war with America’s most hated enemy: Japan (Nathan‚ 2012). There had been thousandths of bloody deaths up to-this-point in the war‚ Japan was destroyed‚ they had just about nothing‚ their country was in starvation
