| Absorption
and emission of radiation by an atom an electron revolving around the
nucleus may capture an incident photon. Once that occurs, the electron is
raised to a higher energy level and thus changes its orbit to a one with a
larger radius |

Chain reaction |
| Fission and Fusion Fission is a nuclear reaction in which an atomic nucleus
splits, or fissions, into fragments, usually two fragments of comparable mass,
with the release of large amounts of energy in the form of heat and radiation.
Energy can also be produced by combining light nuclei in a process is called
nuclear fusion |

by a thin foil made of gold metal |
|
Rutherford experiment
these Java applets show two early models of the atom. A stream of alpha
particles shoot at the atom and are deflected. One models the atom as a jelly of
electrons. The other models it as a nucleus surrounded by electrons |
