Base your answers to questions 82 through 85 on the
information below.

Nuclear fission has been used to produce
electricity. However, nuclear fusion for electricity
production is still under development. The notations of
some nuclides used in nuclear reactions are shown in the
table below.

82 Compare the atomic masses of nuclides
used in fusion to the atomic masses of nuclides used in
fission. [1]
