1. a) Democritus reasoned that if matter could be infinitely divided‚ it was also subject to complete disintegration from which it can never be put back together. However‚ matter can be reintegrated. b) In Greek‚ the prefix "a" means "not" and the word "tomos" means cut. Our word atom therefore comes from atomos‚ a Greek word meaning uncuttable. All matter is composed of atoms‚ which are bits of matter too small to be seen. These atoms CANNOT be further split into smaller portions. 2. At

Decision to Drop the Bomb By Jung Oh Introduction Of all the political and military decisions in history‚ few have been subject to more analysis and comment than the atomic bombings of Hiroshima and Nagasaki (Miles‚ 1985‚121). Scholars in the field have grappled with the vexing question of why the United States decided to use the atomic bomb near the conclusion of the Second World War. A careful study of the critical events leading up to 6 August 1945 offers many distinct explanations. Contemporary

physics professor at Columbia University‚ suggests a clock could be made from a technique he developed in the 1930’s called atomic beam magnetic resonance. 1949 Using Rabi’s technique‚ NIST (then the National Bureau of Standards) announces the world’s first atomic clock using the ammonia molecule as the source of vibrations. 1952 NIST announces the first atomic clock using cesium atoms as the vibration source. This clock is named NBS-1. 1954 NBS-1 is moved to NIST’s new laboratories in Boulder

The Atomic Model has changed over time‚ as the years‚ decades‚ and centuries go by we get a better understanding of the atom and what it looks like. The Atomic Model has changed drastically based on the understanding we have on it‚ each new model has added more information to what we know about it‚ making it easier for scientists and the world to understand. The Atomic Model is a very important part of Science and Chemistry‚ it helps explain the structure and what is inside the atom‚ the particle

The Atomic Bomb: Effects on Hiroshima and Mankind The nuclear bomb was the most devastating weapon ever created by man. It was developed between 1942 and 1945 during the second World War. The project to build the worlds first atomic weapon was called The Manhattan Project. The nuclear bomb was based on the idea of splitting an atom to create energy‚ this is called fission. Three bombs were created‚ "Trinity"‚ "Little Boy"‚ and "Fat Man". "Trinity" was dropped on a test site in New Mexico on July

This investigation will explore the question: To what extent was President Truman’s decision to the drop atomic bomb to save lives and hasten the end of World War Two? The pressures and outcomes of dropping the explosive on Hiroshima and Nagasaki in 1945‚ will be the focus of this investigation. The first source is Thomas Holmes article‚ “The Dropping of the Atomic Bombs on Japan”‚ published in 2005 in the United States. The origin is valuable because Holmes is an American historian and social studies

The Atomic and Nuclear Structure of an Atom The atom has three main components the protons‚ neutrons‚ and electrons. The protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called

the atomic bombs. By doing this‚ there would be many benefits‚ but also some very harsh consequences. The atomic bombs were necessary to end the war because they allowed the US shut things down quickly‚ they assisted the US with showing it’s power‚ and it helped get justice for the soldiers that have already lost their lives fighting for their country. The main reason the US felt the need to drop the atomic bomb was because it was crucial for them to end this war once and for all. The atomic bombs
