Vor 2 Tagen · Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
1. Mai 2024 · Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.
Vor 2 Tagen · Kernenergie, Atomenergie, Atomkraft, Kernkraft oder Nuklearenergie ist die Technologie zur großtechnischen Erzeugung von Sekundärenergie mittels Kernspaltung. Diese Technologie wird seit den 1950er Jahren in großem Maßstab zur Stromproduktion genutzt.
Vor einem Tag · Nuclear fusion is the process that powers active or main-sequence stars and other high-magnitude stars, where large amounts of energy are released. A nuclear fusion process that produces atomic nuclei lighter than iron-56 or nickel-62 will generally release energy.
2. Mai 2024 · Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays, usually by emitting an alpha particle.
Vor einem Tag · 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. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is copper.
1. Mai 2024 · In quantum mechanics, an atomic orbital (/ ˈ ɔːr b ɪ t ə l /) is a function describing the location and wave-like behavior of an electron in an atom. This function describes the electron's charge distribution around the atom's nucleus , and can be used to calculate the probability of finding an electron in a specific region ...
