| Thomson's Atomic Model |
Thomson's atomic model is first atomic model proposed in 1898 related to
atomic structure. This model is similar to water-melon in which
positive charge protons is like pulp in which negative charge electrons
like seeds in water-melon, also known as pudding model. This model is
called Thomson's atomic model.
Drawback of Thomson's atomic model
Thomson's atomic model is unable to explain scattering experiment of Rutherford.
Thomson model of atom
=> Give
by J.J Thomson (1898)
=> According
to J.J. Thomson atoms posses a spherical shape with radius about 10-10 m,
in which + ve charge is uniformly distributed.
=> Electrons
are embedded in such a manner to give most stable electrostatic arrangement.
=> Other
names of this model plum pudding raisin pudding watermelon.
=> Mass
is assumed to be uniformly distributed in atom.
