5 Why do isotopes of the same element have the same chemical properties? B A They have the same nucleon number. B They have the same number of electrons in the outer shell. C They have the same number of neutrons in the nucleus. D They have the same number of protons as neutrons. ...

Why do radioactive isotopes emit radiation? Describe nuclear fusion Why do atomic nuclei decay? How does a cyclotron produce radioisotopes using hydrogen? Where does deuterium come from? Why is binding energy per nucleon constant? Why is Rutherford's model called the nuclear atom?
Why do radioactive isotopes emit radiation? Why does the magnetic force depend on velocity? Why is magnetism a physical property? Why were the subatomic particles discovered in this order: electron, proton, neutron? Why do radioactive isotopes work as tracers?
How do scientists date fossils and artifacts? Relative dating is used to determinea fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, ...
It is important to note that nuclear power plants emit less radioactive material than do coal-fired stations (uranium and other radioactive isotopes are found naturally in coal ash and soot) [9]. The most severe environmental impact associated with nuclear energy is due to the mining of ...
For instance, Magnesium with atom number 12 has 3 stable isotopes out of the 4 isotopes listed, and Selenium with an atomic number of 34 has 6 stable isotopes out of the 7 isotopes listed.The reason for this likely has to do with the nuclear packing of the protons (which are equal in...
atraces of both elements are also present as heavier isotopes. 两个元素踪影也是存在作为更重的同位素。[translate] aVillanueva Perales, A. L.; Gutiérrez Ortiz, F. J.; Barrero, F. V.; Ollero, P. Ind. Eng. Chem. Res. 2010, 49, 2263– 2272[translate] ...
The number of protons in the nucleus of an atom determines what element it is, sothe number of protons is fixed. But, the number of neutrons can vary. Nuclei with the same number of protons but different numbers of neutrons are called isotopes. ... Chemical properties in general do not ...
on the other hand, is pretty much the opposite.It occurs when two atoms collide and then nuclei combine, or fuse, to form a heavier nucleus.This is the reaction that powers the Sun, all stars.So, who can tell me what makes fusion more attractive than fission as an energy source. Julie...
