Chemistry · Bohr model of a hydrogen atom: its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model
Which of the following statements about Rutherford's model of an atom are correc
Which of the following statements about Rutherford's model of an atom are correct? This question has multiple correct options
- A. It considered the nucleus is positively charged.
- B. It established that the \( \alpha \) -particles are four times as heavy as a hydrogen atom.
- C. It can be compared to the solar system
- D. It was in agreement with Thomson's model.
Step-by-step solution
Rutherford's model proposed that the atom consists of a small, dense, positively charged nucleus, which was deduced from the scattering of alpha particles. This is a core feature of the model. Option B is incorrect because the mass of alpha particles was known prior, and option D is false as Rutherford's model contradicts Thomson's plum pudding model. Option C, comparing to the solar system, is also correct but less fundamental; thus A is the single best correct option.
