The Bohr’s Atomic Model | Argumentative Essay | shhss | In 1913‚ a Danish physicist named Niels Bohr put Rutherford’s findings together with the observed spectra to come up with a new model of the atom in a real leap of intuition. I believe that the Bohr’s model of atom explains well about the atomic theory‚ because in his experiments it is shown and explained the structure of an atom. His famous suggestion is about that the electrons orbit around the nucleus of an atom. Bohr experimented

The two bombings‚ killed around 199‚000 people‚ and until today has been the only use use of nuclear weapons in battle. Why did the United States drop an atomic bomb on Hiroshima and Nagasaki and what was the aftermath? After the war in Europe had concluded when Nazi Germany surrendered on May 8‚ 1945‚ and Hitler committed suicide. The Japanese‚ refused to accept the Allies demands for unconditional surrender

The bombs caused survivors to have detrimental psychological ailments which followed them for the rest of their life. Because the atomic bombs were much more powerful that any other bombs dropped before it‚ the consequences were much more serious and widespread. Many survivors of the attacks describe the aftermath of the bombings as a sight of hell‚ or even a “nuclear apocalypse” with the flash of the bombs being so bright and the dust covering bodies‚ both dead and alive (Nicholls‚ 66).

War Against Japan: Science‚ Morality And The Atomic Bomb‚ the author provides information on the war in the Pacific which involved the United States and Japan. After the Japanese attack on Pearl Harbor the United States entered the second World War in 1941. United States gained control of Okinawa in 1945 which meant that the U.S had control‚ in the months of May through August there were major air attacks on Japan‚ the Manhattan Project and the two atomic bombs the United States dropped in Hiroshima

a $2 billion venture. This venture‚ known as the Manhattan Project‚ was a push to deliver a nuclear bomb. This venture was gone up against by gathering nuclear researchers from everywhere throughout the world. President Truman’s choice to drop the atomic bomb on the urban areas of Hiroshima and Nagasaki were the immediate reason for the finish of World War II in the Pacific. The United States felt it was important to drop the nuclear bombs on these two urban areas or it would endure more losses. Not
