understanding upon the structure of the atom. Before Rutherford‚ there was a man named Joseph John Thomson who proposed the structure of the atom. He stated that the electrons of the atoms are actually inside the atom‚ and the atom itself is positively charged‚ like a “raisin pudding”. The electrons are scattered all around the atom. He stated that the electrons and the positively charged material cancel each other‚ making it stable. The structure of the atom‚ proposed by Thomson. (J.J Thomson Plum

bomb would be needed. However Eisenhower stood strong on his opinions and resolved the conflicts without using not only atomic bombs but no military force at all. At the UN’s General Assembly meeting in New York of December‚ 1953 he gave his famous “Atoms for Peace” speech. Just eight years prior the U.S. dropped two atomic bombs in Nagasaki and Hiroshima‚ Japan. This gave lots of international leaders and civilians the belief that if you got on the bad side of the U.S. that they would just nuke you
