In Thomson's plum pudding model the mass of the atom is in the A. electrons. B. matter between the electrons. C. nucleus. D. proton

Which change occurs during a nuclear fission reaction? (1) Covalent bonds are converted to ionic bonds. (2) Isotopes are converted to isomers. (3) Temperature is converted to mass. (4) Matter is converted to energy

A reaction will NOT occur when all the reactants and products in the ionic equation are spectator ions because no change occurs such as the formation of a precipitate or molecular compound.
