Nuclear reaction A reaction in which the nucleus of an atom is changed affecting the identity of that element What are some differences between chemical reactions and nuclear reactions? Elements may be changed in a nuclear reaction but are only rearranged in a chemical reaction What is the strong nuclear force? The force that holds […]

Nuclear Chemistry: Unit 5

Most chemical reactions involve The exchange or shafing of electrons which does not affect the nucleus How is nuclear chemistry different than other chemical reactions? Bc it involves changes in the nucleus Transmutation When the nucleus of one element is changed into the nucleus of a different element Which means the number of protons is […]

Nuclear Chemistry (Notes)

Discovery of Radiation Henri Becquerel 1896 – wrapped photographic film in black paper, put uranium on top and left it in the sun – the photograph was “exposed” so he figured the uranium had absorbed and emitted sunlight – did same experiment on cloudy day…film was still exposed – concluded that uranium was emitting energy […]
