Atomic mass unit

World War II units usually focus on European warfare, however the Pacific theatre proved more representative of the innovative outcomes from the war. The tensions between Japan and America began with the Pearl Harbor attacks on December 7, 1941. The attack killed over 2,400 civilians and servicemen and caused America to finally enter World War II. During the war, Americans created propaganda posters that advertised Anti-Asian ideas and the government set up internment camps for Asians to eliminate

Matter and energy classify the two things to classify the universe. 2. Physicists have done experiments and analysis to come to understand physics. 3. While matter takes up space, energy does not take up space. 4. In the idea of light not taking space and has no mass, it does not have the definition

On the morning of August 6, 1945, a B-29 bomber named Enola Gay flew over the industrial city of Hiroshima, Japan and dropped the first atomic bomb ever. The city went up in flames caused by the immense power equal to about 20,000 tons of TNT. The project was a success. They were an unprecedented assemblage of civilian, and military scientific brain power-brilliant, intense, and young, the people that helped develop the bomb. Unknowingly they came to an isolated mountain setting, known as Los Alamos

The element I am researching is Iron(Fe). Iron could be used in many ways. Iron is a ductile, gray, relatively soft metal and is a moderately good conductor of heat and electricity. 2.It is attracted by magnets and can be readily magnetized. 3. The pure metal is chemically very reactive and rusts readily in moist air, forming red-brown oxides. Rust is iron oxide and when it is hydrated, it rusts. Where did iron get its name? Paragraph 2 “From the Anglo-Saxon word "iron" or "Iren" (the origin

Problem How did the different scientists contribute to the creation of the modern atomic theory? Why would they be accepted? Hypothesis If the scientists improved each other’s theories, then these improved theories helped to create the modern atomic theory. Objectives General: -Analyze how the different theories helped to the creation of the modern atomic theories. Specific: -Compare the different theories and beliefs stated by the scientists. -Determine how the different theories overlap. Introduction

extracted through minerals such as carnalite, langbeinite, and polyhalite minerals. Potassium is also found in the Earth’s crust, and makes up around 1.5 to 2% of the Earth’s crust. Potassium also can’t be found in nature as a free element. Potassium is atomic number 19 in the periodic table and is symbolized as the letter “K” in the periodic table. The element is in Group 1, Period 4 on the periodic table. The element is an alkali metal and has somewhat of silver color to the element. The structure of

light bulbs, and can be combined with other gases to make signs with a greenish-yellow glow. Every element is special because none are ever the same. Even an atoms isotope is different. Krypton’s atomic number is 36. Its atomic mass is 83.798 units. The number of protons in an element, which is also the atomic number, is 36. It also

The atom is a unit of matter, the smallest unit of an element, consisting of a dense, central, positively charged nucleus surrounded by a system of electrons, equal in number to the number of nuclear protons. It consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All electrons bind to the nucleus through an electromagnetic force. A ground of electrons bound together

Einstein was born in Ulm Germany in 1879 and when to ETH Zurich from 1897 to 1900, then to the University of Zurich in 1905. After school he married a women by the name of Mileva Marić from 1903 to 1919 then to Elsa Einstein from 1919 until 1936, Einstein had three children named Eduard Einstein, Lieserl Einstein, and Hans Albert Einstein. Albert Einstein helped the U.S. government during World War 2. Einstein was visiting the U.S. during the rise Adolf Hitler and Einstein being jewish did not return

The atomic bombs great power is created with a chain reaction of the uranium-235’s atom. This isotope is highly radioactive and gives off much radiation and because it is an isotope, the atom is no longer stable. Inside the atom there are four forces occurring
