neutron number उदाहरण वाक्य

उदाहरण वाक्य

1. Then, I would love to have two dots ( corresponding to the neutron number of 176 and 177 ) marked say, red, and labeled 293 Uus and 294 Uus, correspondingly.
2. For example, actinides with odd neutron number are usually fissile ( fissionable with slow neutrons ) while actinides with even neutron number are usually not fissile ( but are fissionable with fast neutrons ).
3. For example, actinides with odd neutron number are usually fissile ( fissionable with slow neutrons ) while actinides with even neutron number are usually not fissile ( but are fissionable with fast neutrons ).
4. These "'isotope tables "'show all of the known isotopes of the chemical elements, arranged with increasing atomic number from left to right and increasing neutron number from top to bottom.
5. Thus, there are no stable nuclei with equal proton and neutron numbers above atomic number " Z " = 20 ( calcium ) and as " Z " increases, the neutron proton ratio of stable isotopes increases.
6. Even in the case of the very lightest elements where the ratio of neutron number to atomic number varies the most between isotopes it usually has only a small effect, although it does matter in some circumstances ( for hydrogen, the lightest element, the isotope effect is large enough to strongly affect biology ).
7. The modern version of Prout's rule is that the atomic mass of an isotope of proton number ( atomic number ) " Z " and neutron number " N " is equal to sum of the masses of its constituent protons and neutrons, minus the mass of the nuclear binding energy, the mass defect.
8. The natural light-element ratio of equal protons and neutron numbers is prevented in beryllium by the extreme instability of toward alpha decay, which is favored due to the extremely tight binding of [ [ helium # The _ related _ stability _ of _ the _ helium-4 _ nucleus _ and _ electron _ shell | ] ] nuclei.
9. In general, the mass number of a given nuclide differs in value slightly from its atomic mass, since the mass of each proton and neutron is not exactly 1 " u "; since the electrons contribute a lesser share to the atomic mass as neutron number exceeds proton number; and ( finally ) because of the nuclear binding energy.
10. A filled shell would have " doubly magic " ( both its proton number of 114 and neutron number of 184 are thought to be magic ) and thus the most likely to have a very long half-life . ( The next lighter doubly magic spherical nucleus is lead-208, the heaviest known stable nucleus and most stable heavy metal .)
