It is said that rutherford presented his model that electrons are stable by saying their is force of attraction towards the nucleus and centrifugal force away from the nucleus. But this was proved wrong. Then how did Bohr explain it?

Expert Answer
Niels Bohr modified the atom structure even more, he realized that electrons in a cloud around the nucleus of an atom, as Rutherford described would quickly spiral down into the nucleus, causing the atom to collapse.
So Bohr proposed a new model of the atom with basic principals:
- Electrons only exist in fixed orbitals (shells) and not anywhere in between.
- Each shell has a fixed energy.
