Question

write the postulates of Bhor's atomic model of 'H' atom and mention it's limitations ​

Answer 1

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,

• (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. Bohr’s model is semi-classical because it combines the classical concept of electron orbit (postulate 1) with the new concept of quantization (postulates 2 and 3).
