Hiroshima: Was Dropping the Atomic Bomb a Military Necessity? On the morning of August 6th‚ 1945 at around 8:16 a.m.‚ the United States dropped the first bomb on Hiroshima. This bomb was given the nickname “Little Boy.” Three days after the first atomic bomb was dropped‚ on August 9th‚ 1945 at around 11:02 a.m.‚ the United States dropped a second atomic bomb on Nagasaki. This bomb was given the nickname “Fat Man.” These two bombs immensely destroyed these cities and took the lives of many people

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

dropped a bomb in Japan. The bombing of Pearl Harbor by the Japanese to initiate United States entrance into the war‚ just four years before‚ was still fresh on the minds of many Americans. A feeling of justification and a desire to end the war strengthened the resolve of the United States to quickly and decisively conclude it. President Harry Truman had many alternatives at his disposal for ending the war: invade the Japanese mainland‚ hold a demonstration of the destructive power of the atomic bomb

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
