![]() Nuclear power plants have a carbon footprint comparable to that of renewable energy such as solar farms and wind farms, and much lower than fossil fuels such as natural gas and coal. However, building a nuclear power plant often spans five to ten years, which can accrue to significant financial costs, depending on how the initial investments are financed. Nuclear plants are very often used for base load since their operations, maintenance, and fuel costs are at the lower end of the spectrum of costs. As of 2022, the International Atomic Energy Agency reported there were 422 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. Molecules: smallest particle of a compound that has all the compound's chemical properties.A nuclear power plant ( NPP) is a thermal power station in which the heat source is a nuclear reactor.Compound: chemical combination of elements.antiprotons have the same mass as protons but are negatively charged.positron has the same mass as an electron and the same magnitude of charge but the opposite sign.antimatter is composed of atoms with negative nuclei and positive electrons, or positrons.Deflection of alpha particles showed the atom to be mostly empty space with a concentration of mass at its center Ernest Rutherford 1871 - 1937.Millikan Oil Drop Experiment Robert A.Atoms of the same element that contain different numbers of neutrons are isotopes.most iron nuclei with 26 protons contain 30 neutrons, while a small percentage contain 29 neutrons.small percentage contain one neutron and a smaller percentage, two neutrons.all hydrogen nuclei have a single proton but most have no neutrons. ![]() number of protons in the nucleus need not match the number of neutrons there.number of protons in a nucleus exactly matches the number of electrons around the nucleus in a neutral atom,.mass of an electron is so small that it's disregarded.mass of an atom in atomic mass units is simply the sum of its protons and neutrons and is known as the atomic mass number.approximate mass of a single proton or neutron is 1 amu.(Nucleus) BB on the 50 yard line with the electrons at a distance of about 50 yards from the BB.Doritos are orbiting the cars at a distance of a few miles.Electrons are like bags of doritos (1 lb objects).Nucleons (protons and neutrons) are like toyotas (2000 lb cars).About 6 years for one of your exhaled breaths to become mixed in the atmosphere As many atoms in a breath of air as breathfuls of air in Earth’s atmosphere.About 1023 atoms in a thimbleful of water.Strong nuclear force – only apparent at distances of 1 – 2 femtometers (10-15m).Since like charges repel, how are the protons bound together in the nucleus?.Actually, protons and neutrons can be further split into quarks.Atoms composed of protons, neutrons, and electrons.In particle accelerators and in stars, subatomic particles can be found.Greek origin – atomos which means indivisible. ![]()
