 Rutherford’s gold foil experiment

• Video! Rutherford’s Gold Foil Experiment

shot a stream of alpha particles at a sheet of very
thin gold foil which stood in front of a screen.

• In Rutherford's experiment, a radioactive source
shot a stream of alpha particles at a sheet of very

– The alpha particles would make small flashes of light
where they hit the screen.

• Since some of the positive alpha particles
were substantially deflected,

were substantially deflected, Rutherford
concluded that there must be something
inside an atom for the alpha particles to
bounce off of,

It has to do with the uncertainty principle.

-The electron cannot have a defined position
in the nuclei of atoms means that it must occupy
every other space within the atom in a wave of
possibilities.

-The electron cannot have a defined position
in the nuclei of atoms means that it must occupy
every other space within the atom in a wave of
possibilities.
Pauli exclusion principle: The principle that two fermions
of a given type, such as electrons, protons, or neutrons,
cannot occupy the same quantum state. It does not apply
to bosons. This principle plays a key role in the electron
orbital structure of atoms, since it prevents more than two
electrons from occupying any given orbital (two are
allowed, since they may have opposite spin, and thus be
in different quantum states)
More difficult explanation.
