Historical Development of Atomic Structure Yazan Fahmawi Sept. 30‚ 1995 T3 IBS Chemistry Ms. Redman The idea behind the "atom" goes back to the Ancient Greek society‚ where scientists believed that all matter was made of smaller‚ more fundamental particles called elements. They called these particles atoms‚ meaning "not divisible." Then came the chemists and physicists of the 16th and 17th centuries who discovered various formulae of various salts and water‚ hence discovering the idea of a molecule

Truman and the Atomic Bomb On August 6th‚ 1945‚ the atomic bomb‚ named “Little Boy”‚ was dropped over Hiroshima‚ Japan. There were reasons for this act against Japan‚ one of which having to do with Russia. These included strategic‚ moral‚ and political reasons that would benefit the US in the war and ultimately help them win. The US also wanted this to end World War 2. As we look back on this historical event‚ many would argue if dropping the atomic bomb was the right choice. Strategically and politically

the 1945 the United States of America dropped atomic bombs on Japan. What if the United States shared their knowledge of Atomic energy with the rest of the world and it became the main resource of the world. Atomic energy would be used to power cars‚ houses‚ even phones. The world would advance probably in a bigger more clucky way. Things would need to be bigger because its all powered by atomic energy. There would be a lot less pollution because Atomic energy is all clean. Nations would not invade

Meitner‚ Ernst Marsden‚ and Hans Geiger. All of these physicists impacted the development of the atomic theory one way or another. Albert Einstein was a German physicist who moved to America to share his knowledge about the atomic theory. In 1905‚ he wrote a famous paper that concerned tiny particles and how they moved in a liquid or gas. Einstein took Brownian motion(Browns law) and confirmed the atomic theory of matter by the use of Brownian motion. This was some of the first proof that atoms actually

It was lead by Major General Leslie Groves of the U.S. Army Corps of Engineers and physicist J. Robert Oppenheimer‚ who was the director of the Los Alamos National Laboratory. The program was hurried along after the United States government saw the importance and possibilities of the atomic bomb.

Atomic Spectroscopy using a Constant Deviation Spectrometer with Fabry-Perot Etalon Abstract A constant deviation spectrometer with Fabry-Perot etalon has been used to investigate the various atomic emission characteristics from a Zn-Cd-Hg lamp‚ a low pressure Hg lamp and a Ne lamp. The Fabry-Perot etalon of Free Spectral Range 0.010 cm-1 was used to resolve the fringes of the Hg 546.0731nm spectral line‚ and the 594.4834nm‚ 614.3063nm‚ 640.2246nm and 650.6528nm spectral lines of the Ne lamp
