Answer 1

Answer:

Bohr's model of the atom postulates that electrons can only revolve in precise discrete orbits of specific radii, called 'stable orbits. ' While revolving in the stable orbits, the centripetally accelerated electrons do not radiate any energy. Hence, the atoms remain stable and exist in a 'stationary state.

Answer 2

QUESTION⤵️

state and Explain Bohr atomic model?

ANSWER⤵️

This model was based on Quantum theory of radiation and classical laws of physics.

Bohr model is applicable only for single electron species like

H,

$He {}^{ + }$

$Li {}^{2 + }$

etc...

Bohr model is based on particle nature of electron.

COULUMBIC FORCE= Kq1q2/r^2

CENTRIFUGAL FORCE= mv^2/r

ANGULAR MOMENTUM= mvr

IMPORTANT POSTULATES:::-

⚫ 1ST ➡️

atom has a nucleus where all protons and neutrons are present and is situated at the centre of the atom.

⚫2nd ➡️

negatively charged electron revolve around the nucleus in the same way as the planets revolve around the sun.

the path of electron is circular.
