in hydrogen bombs. Scientists are still trying to harness this reaction for domestic
uses. The following examples show basically how the reactions occur.
EXAMPLES:
Two deuterium atoms combining
Tritium combining with hydrogen
The energy released in a nuclear reaction (either fission or fusion) comes from the
fractional amount of mass converted into energy. Nuclear changes convert matter
into energy. Energy released during nuclear reactions is much greater than the
energy released during chemical reactions.
CHAPTER SUMMARY
The following terms summarize all the concepts and ideas that were introduced in
this chapter. You should be able to explain their meaning and how you would use
them in chemistry. They appear in boldface type in this chapter to draw your
attention to them. The boldface type also makes it easier for you to look them up if
you need to. You could also use Internet search engines like google.com on your
computer to get a quick and expanded explanation of these terms, laws, and
formulas.
