Question

Which of the following sentence is wrong about Rutherford Model?

• A. The size of nucleus is very big as compared to the size of the atom as a whole.
• B. The nucleus is centrally located positively charged mass.
• C. Electrons revolve in circular orbits in space available around the nucleus.
• D. An atom is electrically neutral.

Answer 1

The correct option is A The size of nucleus is very big as compared to the size of the atom as a whole.

Rutherford conducted an experiment in order to find the arrangement of electrons and protons in an atom. Based on this observation, Rutherford proposed a model for the structure of the atom which describes the model as:
1. The nucleus is centrally located positively charged mass.
2. The entire mass of an atom is concentrated in it.
3. It is dense part of the atom and the size of the nucleus is small when compared to the size of the atom as a whole.
All the other options given in the question is correct.
