Atomic mass unit

who was the first individual to utilize the term atom. He imagined that if you take a bit of matter and divide it and keep on dividing it, you will eventually come to a point where you could not isolate it any longer. This principle or fundamental unit was what Democritus called an atom. He called this the theory of the universe: • all matter compromises of atoms, which are bits of matter too little to be seen • there is an unfilled space between atoms • atoms are completely solid • atoms have

Independent Study Unit Hiroshima and Nagasaki: The Terror that Saved Millions       The atomic bomb and it's use over the two Japanese cities of Hiroshima and Nagasaki is still a source of heated debate even over fifty years later. Many people on both sides -Japan and The United States- hold the belief that Truman's decision to drop the bomb was a mistake and that under no circumstances should such drastic measures be taken in war. What these people do not realize are the

“B”. Boron is in group 13 of the periodic table which is called, “The Boron Group”, since Boron is the first element of group 13. It is also a Period 2 element. Boron is a solid. It also has 2 energy shells. Boron’s atomic number is 5 and its atomic mass is 10.811 atomic mass units. Also, it has 5 protons, 5 electrons, and 6 neutrons. It is a powder, but the powder is still a solid. It has a color that you can see in iron fillings - sort of like graphite from the lead in a pencil. The graphite of

Research Paper 1 ESS 102 Scott An Project Orion Synopsis The purpose of this research paper is to explore the use of nuclear propulsion in Project Orion and future uses. Project Orion intended to use numerous atomic bombs for propulsion. The history of the project will be explained as it was short lived, but its technology led to new source energy for spacecraft, nuclear energy. Project Orion was meant to be used for peaceful purposes only, but it can also potentially be used as a weapon of war

25 1.81 0.85 30 2.15 0.98 A study was performed to determine the diffusion rate of two substances. One crystal from each substance was placed in separate medium filled Petri dishes. Substance A has a molecular mass of 164 atomic mass units (amu) and substance B has a molecular mass of 326 amu. ? According to the table, how far could you expect substance A to diffuse in 12.5 minutes? a. 0.22 cm b. 0.39 cm c. 0.95 cm* d. 1.31 cm ? At which time interval is diffusion difference the greatest between

to drop the atomic warheads on America's enemy, yet in the end after all is said and done America was simply defending her land and right for freedom. America was under attack in a war fought on foreign soil. No one wanted the war to be brought on American soil and all American's wanted the war to be over to assure safety of the American people.

The Atomic Bomb and the Manhattan Project It was December 7, 1942 a beautiful mourning in Pearl Harbor. When out of the blue, hundreds of Japanese planes bomb and either sunk or severely damaged eight battle ships and at least thirteen other naval ships that were docked on the shore. This spark is what involved the United States the forest fire known as World War II. My paper is not on the war itself, but is on the atomic bomb, and what was known as the Manhattan project. In my report I will talk
