a. What are the limitations of Rutherford’s Model of Atom.
b. What are the limitations of J.J. Thomson’s Model of Atom.
Answers
Explanation:
Rutherford's experiment was unable to explain certain things. They are: Rutherford's model was unable to explain the stability of an atom. According to Rutherford's postulate, electrons revolve at a very high speed around a nucleus of an atom in a fixed orbit.
Thomson's atomic model failed to explain how the positive charge holds on the electrons inside the atom. It also failed to explain an atom's stability. The theory did not mention anything about the nucleus of an atom. It was unable to explain the scattering experiment of Rutherford.
Question :-
a. What are the limitations of Rutherford's model of an atom?
b. What are the limitations of J.J. Thomson’s Model of Atom.
Answer :-
a. According to Rutherford’s model of an atom the electrons are revolving in a circular orbit around the nucleus. Any such particle that revolves would undergo acceleration and radiate energy. The revolving electron would lose its energy and finally fall into the nucleus, the atom would be highly unstable. But we know that atoms are quite stable.
b. According to J.J. Thomson’s model of an atom, the electrons are embedded all over in the positively charged spheres. But experiments done by other scientists showed that protons are present only in the centre of the atom and electrons are distributed around it.
