Question

1) Name the model that displaced Thomson’s model of an atom.
2) Was this model able to explain the stability of an atom? Explain the
salient features of this model.
3) Zain wants to know how electrons are able to maintain their position in
the orbits. Help him to understand the reason behind this.
on the bases of ATOMIC STRUCTURE

Answer 1

Answer:

1. Rutherford's atomic model

2. No, Rutherford's model not fully explained the stability, as it unable to prove rotation of electrons in orbital paths.

●Salient features-

1. It defines nucleus and give its existence

2. It proves that there is much vacant space in an atom

3. It explained the stability of an atom to some extent

4. It also provides nature of nucleus

3. Electrons are able to maintain the position due to effect of electrostatic attraction between nucleus and electrons & centrifugal force develops due to rotation. This is clarified by Bohr's atomic model and further developments by other scientists.
