Quite a few scientists have helped to create and extend ideas on what an atom is and what its components are. One of these discoverers‚ John Dalton‚ developed the first modern atomic theory. Although much of his theory is still true today‚ one point was disproved by Ernest Rutherford. Dalton’s atomic theory had several parts to it. He believed atoms were indivisible‚ or impossible to break down into smaller particles. Also‚ he said elements are all consisted of atoms and that the atoms of

United States dropping on atomic bomb on Hiroshima was one of the most controversial topics of 1945. Many believe that the United States decision to drop this atomic bomb on Hiroshima‚ was a diplomatic measure intended to scare the Soviet Union after the Second World War; however‚ this is untrue. The United States decision to drop the atomic bomb on Hiroshima was done entirely to scare the Japanese army‚ and force them to surrender. The United States choice to drop the atomic bomb‚ strictly for the

The effects of the atomic bomb were terrible. There’s no doubt in my mind that the atomic bombs dropped on Hiroshima and Nagasaki were a costly mistake. Atomic bombs produce heat millions of degrees high‚ and visible ultraviolet and inferred rays.(Lapp 844) Everyone and everything exposed to their blast is affected. No one is left untouched‚ whether it be emotional or physical; in many cases both. However‚ many members of the science community argue that the atomic bomb was a great advance in technology

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

Was the Atomic Bombing Justified? The Atomic Bomb made a very serious statement at a time when the world was in disarray (“Manhattan”). World War II was one of the most destructive times in history causing over 50 million deaths and leaving behind mental and physical casualties of war. (“World War II”) It started in September‚ 1939 when Germany invaded Poland and continued on a destructive path through Europe. Britain and France declared war on Germany. Two years prior in 1937‚ the Sino Japanese

had every right to drop the Atomic bomb on Japan and therefore force them to surrender. The Japanese had at that time‚ already lost quite a lot of battles against the US and were forced to retreat back to Japan. Yet‚ the Japanese borders were heavily fortified. Had the Americans attacked Japan‚ they estimated their losses to be about 500 000 men. By dropping the atomic bomb‚ an estimated number of 100 000 people died. So in the end you can see that dropping the atomic bomb has saved quite a lot of

The objective of this lab is broken into two parts. The first is to recognize the principles of flame ionization and atomic spectra. The second is to observe and thus further understand the line spectra for multiple elements or molecules as well as determine the correlation between emission spectra and atomic structure. Experimental Procedure Procedure 1: Observation of Line Spectra by Discharge Tubes Six discharge lamps were selected – argon‚ carbon dioxide‚ helium‚ hydrogen‚ iodine‚ mercury‚ and

The story of the atomic bomb Have you ever wondered about how the disasters at Hiroshima and Nagasaki came about? Well I have too‚ and here is what I got for answers.The atomic bomb was built out of necessity in order to protect our country because we found out that the Germans had already discovered nuclear fission‚ it was possibly the most devastating project in the U.S‚ and it also opened up important new studies of radiation. The first atomic bomb was built out of necessity because Albert

neutron of an atom to split the nucleus into smaller parts‚ resulting in two different elements and energy. This process was called fission‚ and it was the basis for the atomic weapons designed and created for use in the Second World War. In early 1939‚ German physicists found a way to split a uranium atom‚ paving the way to atomic weaponry. Out of fear from the power in the enemy hands‚ Albert Einstein‚ a German physicist escaping Nazi rule ‚ and Enrico Fermi informed President Franklin D. Roosevelt
