Question
What are the fundamental contributions of E. Rutherford in understanding the structure of atom?
Solution
Fundamental contributions of E. Rutherford in understanding the structure of the atom are:
(i) There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus.
(ii) Most of the mass is concentrated at the nucleus. The electrons revolve around the nucleus in circular paths.
(iii) The size of nucleus is 105 times smaller than the atom.
