Question

Any two postulates of Bohr bury scheme

Answer 1

Answer:

1. In an atom, the electrons revolve around the nucleus in certain definite circular paths called orbits, or shells.

2. Each shell or orbit corresponds to a definite energy. Therefore, these circular orbits are also known as energy levels or energy shells.

Answer 2

Answer:

Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. ... 3rd energy level is M shell4th energy level is N shell and so on.
