On the basis of the results of
α-scattering experiment, Rutherford suggested the following picture of the
atom:
·
Atom may be regarded as a sphere of diameter 10–10 m
but whole of the positive charge and almost the entire mass of the atom is
concentrated in a small central core called nucleus having diameter of about 10–14
m.
·
The nucleus is surrounded by electrons. In other words, the
electrons are spread over the remaining part of the atom leaving plenty of
empty space in the atom.
