Calculate the number of neutrons emitted when .(92)U^(235) undergoes controlled nuclear fission to .(54)Xe^(142) and .(38)Sr^(90).
This total is called the mass number, A. The number of neutrons in an atom, the neutron number, is given by the quantity A-Z.The term element refers to, a pure substance with atoms all of a single kind. To the chemist the "kind" of atom is specified by its atomic number, since ...
