Question

2. How is emission of radiation from an atom explained by Bohr's modei?​

Answer 1

Answer:

Bohr's model explains the spectral lines of the hydrogen atomic emission spectrum. While the electron of the atom remains in the ground state, its energy is unchanged. When the atom absorbs one or more quanta of energy, the electron moves from the ground state orbit to an excited state orbit that is further away.

Answer 2

Explanation:

Bohr’s model of the hydrogen atom is based on three postulates:

(1) an electron moves around the nucleus in a circular orbit,

(2) an electron’s angular momentum in the orbit is quantized, and

(3) the change in an electron’s energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon.
