Question

what are the postulates of Bhor,sModel of atom​

Answer 1

ANSWER :-

$The \: following \: postulates \: \: of \\ Bohr's \: atomic \: model \: are \\ as \: follows \: --$

• In an atom the centre part consists of nucleus and the electrons revolve around it.

• Electrons revolve around the nucleus in certain fixed, circular, concentric orbits which are known as stationary orbits.

• The stationary orbits are only those in which the angular momentum of the electron in that orbit is an integral multiple of (h/2π).

• Energy is observed when electron jumps from lower to higher shell means if electrons shift from second shell to the third shell then gain energy.

• Energy is released when electron jumps from higher to lower shell means if electron goes from the third shell to the second shell then it loses energy.

Postulates of Bohr's Model of an Atom

Postulates of Bohr's Model of an AtomIn an atom, electrons (negatively charged) revolve around the positively charged nucleus in a definite circular path called orbits or shells. Each orbit or shell has a fixed energy and these circular orbits are known as orbital shells.
