Cloud Model - an atom is comprised of a nucleus made up of neutrons and protons‚ and electrons moving extremely fast around the nucleus‚ forming an electron cloud instead of moving in orbits like what Bohr’s model suggests - proposed by Erwin Schrodinger in 1926‚ when he derived this model using a mathematical equation that he himself made http://1.bp.blogspot.com/-LEqGPr4h8R4/TsgJyT6vP6I/AAAAAAAAAKE/pTl6O3V2u0M/s200/electron_cloud_model.jpg The Planetary/Bohr’s Model - an atom is comprised of

particles called atom. He tried to break down matters into smallest particles. His model was that the matter would stop splitting in halves when it reaches its smallest matter. He called that an atom. * John Dalton In 1803‚ John Dalton proposed a theory. The theory had 4 parts into it. 1. Elements are made of identical atoms. 2. Atoms of different elements are physically different 3. Compounds are formed by a combination of two or more different kinds of atoms. 4. A chemical

The Manhattan Project World War II started on September 1 1939‚ when Germany attacked Poland. By 1941‚ the Germans were ahead in the race for the atomic bomb. They had a heavy-water plant‚ high-grade uranium compounds‚ capable scientists and engineers‚ and the greatest chemical engineering industry in the world. Even before its entry into the war‚ the United States had become very concerned with the nuclear threat of the Axis powers. On October 11‚ 1939‚ President Franklin D. Roosevelt received

If we go back to the history of 1945‚ we come to know the history of 1945; we come to know the worst type of nuclear disaster the world had witnessed. On August 6‚ 1945 an atom bomb was dropped on HIROSHIMA in Japan‚ which devastated the entire town killing 66‚000 people and injuring nearly 69‚000. On August 9‚ 1945 another atom bomb was dropped on NAGASAKI. This bomb killed nearly 39‚000 people and injured more than 25‚000. Nuclear weapons are thus‚ far more destructive and harmful to the society
