Finding atomic makeup: One of the isotopes of uranium used in nuclear power plant is ._(92)^(235)U . Ho many protons, neutrons, and electrons does an atom of ._(92)^(235)U have? Strategy: The number at the bottom left of the element's symbol is the atmoic number indicaring atom. from the mass number at the top left, we know the number of nucleous (protons plus neutrons). Thus, the number of neutrons equals the difference between the mass number (superscript) and atomic number (subscript).

If 200 MeV of energy is released in the fission of 1 nucleus of ._(92)U^(235) , the number of nuclei that undergo fission to produce energy of 10 kWh in 1 s is

A slow neutron strikes a nucleus of ._(92)^(235)U splitting it into lighter nuclei of ._(56)^(141)Ba and ._(36)^(92)Kr along with three neutrons. The energy released in this reaction is ( The masses of uranium, barium and krypton of this reaction are 235.043933,140.917700 and 91.895400 u respectively. The mass of a neutron is 1.008665 u

What may be the new neutron and proton ratio after a nuclide ._(92)U^(238) loses an alpha -particles?

A slow neutron strikes a nucleus of ._(92)U^(235) splitting it into lighter nuclei of barium and krypton and releasing three neutrons. Write the corresponding nuclear reaction. Also calculate the energy released on this reaction Given m(._(92)U^(235))=235.043933 "amu" m(._(0)n^(1))=1.008665 amu m(._(56)Ba^(141))=140.917700 "amu" m(._(36)Kr^(92))=91.895400 amu
