Kevin Li Mrs. Baldwin Honors Chemistry 3 November 2012 Historical Development of Atomic Structure Over the many years of the world’s history‚ there have been numerous developments and discoveries pertaining to atomic structure. Each of these breakthroughs gradually led us—step by step—to a deeper understanding of what makes up each and every atom. Because of this‚ our perception of an atom’s structure today is vastly different from the first idea of an atom’s structure from many centuries

everything happens for a reason”. When president Truman and his advisors made the decision to drop the atomic bomb‚ they thought it would end the war. The dropping of the atomic atomic bomb had many successful tactics. It created great peace for the US from the fact that it ended total war. After the US had lost millions to the war‚ it was ready to make a change to end all war. Good things did come from the atomic bomb‚ like the fact that it ended World War II. The amount of peace for the US got for dropping

Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third‚ all the atoms were different from all the other atoms. Fourth‚ atoms of different elements combined together in equal numbers to form compounds. Fifth and final

Why did the Truman Administration decide to drop the atomic bombs on Japan in 1945? There has been much debate as to why Truman elected to drop the atomic weapons on Hiroshima and Nagasaki in the summer of 1945. Historians have long debated the true purpose to which the atomic bombs were designed to fulfil upon there deployment. The Alperovitz thesis of the 1960 was accepted for many years. The thesis revolved around the idea that the atomic weapons were deployed as diplomatic tools to intimidate

DBQ ESSAY In Europe‚ the war with Germany was over but Japan was still fighting. So the U.S could concreted on the war with Japan.

So on August 1945 the U.S decided to drop atomic bombs on the Japanese cities of Hiroshima and Nagasaki and this created some controversy. Some people though it was a good idea to bomb Japan‚ while others say that 200‚000 innocent people

It was estimated that invading Japan with a normal attack would cost 1.2 million casualties (Source #2‚ see annotation). This was one of the most prevalent factors in President Truman’s decision to authorize the use of the atomic bomb. The other leading influence on the atomic bomb’s justification was the Japanese

Chemistry Atomic Structure: The Electron A myriad of trends occur on the periodic table‚ whether it is defined through the size of the atoms or the first ionization energy that may occur‚ many other trends can be found simply looking horizontally or vertically on to the table. As you look from left to right you can see that the reactivity of the elements increase‚ this is due to the number of electrons increasing on the shell. This also once you go down the table; the shells become further and

The dropping of the atomic bomb on Japan is significant in many ways as it was a start of a new age of warfare. The dropping started a long journey into accepting that the world was going to advance technology. The dropping of the bomb made countries fear each other but it also stopped world war two. The impact of the atomic bomb on Japan is a reason why the bomb was significant because they were the trial run. The atomic bomb was powerful and caused suffering to thousands of people. The first bomb

Ryan Parmelee History 1302 Dr. Cox Atomic bomb In 1945 Harry S. Truman decided to use the atomic bomb not only once‚ but twice to finish World War Two. The first bomb that was dropped on Hiroshima August‚ 6th killed upwards to around 80‚000 people and the second bomb dropped on Nagasaki August‚ 14th killed 40‚000 people. The controversy of the atomic bomb is because of the amount of innocent people that were killed in Japan. Nobody will ever know the outcome of the war if we never dropped the

The Development of the Atomic Theory Have you ever wondered how the atomic theory came to be? Or have you have wondered who it was that helped in its development? There was not just one man who came up with the atomic theory‚ but there were many scientists that contributed to its development. One of these scientists was Democritus‚ a Greek philosopher. Democritus was the son of Hegesistratus‚ and he was a student of Magians and Chaldaeans. By some authorities he was thought of as the greatest
