What if we could produce the electricity
we need without all of the pollution and
other disadvantages associated with the
use of fossil fuels? As we become
increasingly aware of how fossil fuel
supplies are limited, and how much their
Nuclear Energy: combustion contributes to air and land
Introduction pollution, we are increasingly on the
look-out for alternative sources of
energy.
There are some alternatives. Nuclear
energy relies on harnessing the energy
produced by special chemical reactions.
It does not burn anything, so it does not
produce the carbon dioxide, sulfur, and
mercury pollution of fossil fuels. Could
nuclear energy be our next best bet?

for yourself.
nucleus the number of protons and neutrons in
an atom's nucleus
protons The nucleus of an atom that is ___ will
spontaneously break down.
element parts of an atom with positive charge
,atomic number Atoms of the same always have the
same number of protons.
isotopes the central part of an atom
mass number atoms of the same element with
different numbers of neutrons in their
nuclei
radioactive the number of protons in an atom's
nucleus
Nuclear energy is produced when
changes take place within the nuclei of
Tutorial: Nuclear certain atoms. These changes take place
Changes when the nuclei of some isotopes
spontaneously change, or are made to
change, into nuclei of different isotopes.
There are two types of nuclear changes.

Nuclear power plants Unlike power plants that burn carbon-rich fossil fuels,
compare to those that nuclear power plants do not burn any fuels. Since no
burn fossil fuels in terms of carbon-bearing fuels are burned, nuclear power plants
