Question

what is difference in tha atomic model of Thomson and Rutherford?​

Answer 1

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons while Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.

Understanding the atomic structure was started with Thomason’s model, where he considered that the atom is like a plum having a uniform positive charge distributed throughout the structure and then the electrons were embedded in it just like resins.

The second attempt was made by Rutherford where he proposed that every atom has a positive charge concentrated at a point and named it as the nucleus.

Unlike Thomason Rutherford believed that the electron revolve around the nucleus as the planets do around the sun.

He also performed a scattering experiment using

1/3000 thick gold foil.
