All uranium atoms have 92 protons. U-238 is the most common isotope of uranium, making up 99.3% of naturally occurring uranium. The 238 refers to the atomic weight of the isotope, which equals the total number of protons plus neutrons in its nucleus. Thus U-238 has 238 – 92 = 146 neutrons. Fusing hydrogen nuclei to make helium releases huge amounts of energy. In a fusion reaction, energy is released when two light atomic nuclei are fused together to form one heavier atom. This is the process that powers the Sun and other stars, where hydrogen nuclei are combined to form helium. To achieve fusion, the fuel must be heated to Nuclear Batteries could also play a major role in addressing the plight of informal settlements and slums. Currently, over a billion people do not have access to electricity for cooking, lighting Electrons and a compact nucleus of protons and neutrons. The atom is the basic particle of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically-bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. Energy is a measurement of the ability of something to do work. It is not a material substance. Energy can be stored and measured in many forms. Although we often hear people talking about energy consumption, energy is never really destroyed. It is just transferred from one form to another, doing work in the process. The Manhattan Project. Part of the Einstein exhibition. In 1938, three chemists working in a laboratory in Berlin made a discovery that would alter the course of history: they split the uranium atom. The energy released when this splitting, or fission, occurs is tremendous--enough to power a bomb. But before such a weapon could be built TsjMAN. An atomic bomb, codenamed "Little Boy," was dropped over Hiroshima Japan on August 6, 1945. The bomb, which detonated with an energy of around 15 kilotons of TNT, was the first nuclear weapon While controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. Uranium is a heavy metal which has been used as an abundant source of concentrated energy for over 60 years. Uranium occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the Earth's crust as tin, tungsten and molybdenum. Uranium occurs in seawater, and can be recovered from the oceans. There are three factors that help in the prediction of the trends in the Periodic Table: number of protons in the nucleus, number of shells, and shielding effect. Various periodic trends (CC BY-SA 4.0; Sandbh via Wikipedia) Certain properties—notably atomic radius, ionization energy, electron affinity and metallic character—can be The energy you need is equal to the energy that holds the thing together in the first place; and it's called the binding energy. It's the source of the energy we can make by joining small atoms together or splitting big ones apart. It's where nuclear energy comes from.
