Chemical reactions
-one substance changes into another, bas atoms never change their identity
- Orbital electrons are involved as bonds break and form, nuclear particles do not take part.
- reactions are accompanied by relatively small chnages in energy and no change in mass.
- Reactions rates are influenced by temperature, concentration, catalysts, and the compoud in which an element occurs.
Nuclear reactions
-atoms of one element typically are converted into atoms of another element
-protons,neutrons, and other particles ar involved; orbital electrons rarely take part.
- reactions are accompanied by large changes in E and change in mass.
- reaction rates are affected by # of nuclei, not temp, catalysts, or the compoud in which and element occurs.
