What are 5 examples of nuclear energy?
Nuclear Energy divides into Nuclear Fission as exemplified by the Atomic Bomb and our nuclear power reactors and Nuclear Fusion as exemplified by our Sun, all of the stars in our universe, and the hydrogen bomb. Fusion combines lighter nuclides into heavier nuclides, such as hydrogen to helium, losing some mass and releasing some energy as part of the fusion. Stars fuse hydrogen to helium. Heavy stars move to fusing helium to carbon, then carbon to neon, neon to oxygen, oxygen to silicon, and finally silicon to iron 56. Iron 56 is the end of the line. All available fusion energy has been wrung out. The alternate to fusion is nuclear fission, which splits heavier nuclides into lighter daughters, losing some mass and gaining some energy as part of the fission. For example uranium 235 can absorb a stray neutron and become uranium 236 which then fissions into daughter nuclides plus two stray neutrons. The stray neutrons released by the fission can excite other U235 atoms, thus the chain reaction. Some mass is lost and energy is released. Also, radioactives such as iodine 131 are manufactured and used in medical diagnostics such as renal testing and thyroid uptake testing.
What atom had 26 protons 26 electrons and 30 neutrons?
Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.
How many protons neutrons and electrons does iron 56 have?
Iron-56 has 26 protons, 30 neutrons, and 26electrons.
Which atomic mass is the threshold value below which fusion may occur?
56
Iron-56 mass number?
Iron is a metal element. Atomic mass of it is 56.
What iron isotope is the lightest?
Iron 56 is the lightest
Which atomic number is the threshold value which fusion will occur?
56
This is the element Iron. How many protons does Iron have?
iron has 26 protons
Which atomic number is the threshold value below which fusion will occur?
56
How are most of the elements with nuclei heavier than those of hydrogen and helium formed?
Well, Helium is an element, and "substance" can mean a combination of elements and compounds... which are formed according to their chemical properties. Assuming you were asking about pure elements, rather than substances, all elements up to Iron-56 are formed by nuclear fusion, presumably inside of stars. This is due to to Iron-56 being the most stable nucleus in the periodic table. Hydrogen-1 forms Helium-4, Helium combines to form Beryllium-8, Carbon-12, and Oxygen-16. And so on.... up to Iron-56. Fusion of heavier compounds will not result in excess energy (e.g. a star's heat and light) so those nuclear reactions will not sustain a star. Therefore, all elements heavier then Iron-56 are formed by the extraordinary conditions of a super nova. Because earth has abundant elements heavier than Iron-56, it is thought that the matter in our Solar System has been through several solar cycles... In other words, "we are all made of stars".
How many circuits is a nuclear power station?
56
What can supernovas create?
A Supernova explosion will seed the surrounding space with all of the elements created by nuclear fusion in the various layers of the star that preceded the explosion. Nuclear fusion produces less and less energy the heavier the elements used. Once a supergiant star develops a core of Iron and Nickel 56 there is little or no energy being produced by fusion and the star collapses under its own gravitational force causing extreme heat and pressure and then a rebound explosion. This happens in seconds or less. Other products of this supernova are radiation and sub-atomic particles. The heaviest elements produced (Iron and Nickel) accrue neutrons thereby increasing their atomic weight and number and producing heavier and heavier elements. The heavier an element (or metal), the more rare it is. Neutron acquisition can be be either rapid (R-process) or slow (S-process).
