Question

how quantum theory helped bhor's to explain the stability of atom​

Answer 1

Answer:

Bohr turned to Planck's quantum theory to explain the stability of most atoms. He found that the ratio of energy in electrons and the frequency of their orbits around the nucleus was equal to Planck's constant (the proportion of light's energy to its wave frequency, or approximately 6.626 x 10-23 ).

Answer 2

$\huge\fbox\red{Answer:-}$

• He postulated that the angular momentum of the electron is quantized

• It can have only discrete values.

• He assumed that otherwise electrons obey the laws of classical mechanics by traveling around the nucleus in circular orbits.

• Because of the quantization, the electron orbits have fixed sizes and energies.
