Bohrs atomic model assumes :

Question

Verified by Toppr

Answer 1

Bohr's Assumption :
( i ) Electron in atoms orbit the nucleus.
( ii ) Electron in a quantized orbit will not radiate energy.
( iii ) Electrons can only gain and lose energy by jumping from one allowed orbit to other.
He also assumed one of the postulates of Rutherford's atomic model, that is, the mass of the nucleus is very large compared to that of the electrons and hence assumed to be infinite

Answer 2

Bohr's Assumption :
( i ) Electron in atoms orbit the nucleus.
( ii ) Electron in a quantized orbit will not radiate energy.
( iii ) Electrons can only gain and lose energy by jumping from one allowed orbit to other.

Bohrs atomic model assumes :

the nucleus is of infinite mass and is at rest

electron in a quantized orbit will not radiate energy

mass of the electron remains constant

all of the above

Bohr's atomic model cannot be used to explain multiple electron species.

It does not take inter-electronic interactions into account.

Bohr's atomic model cannot be used to explain multiple electron species.

In Bohr's model of hydrogen atom,

Out of the following which one is not a possible energy for a photon to be emitted by hydrogen atom according to Bohr's atomic model ?

Assume a neutron and an electron bound to each other by gravitational force. Assuming Bohr's quantization rule. Find the expression for $n$ th energy level.

A diatomic molecule has moment of inertia $I$ . By Bohrs quantization condition its rotational energy in the $n^{t h}$ level ( $n = 0$ is not allowed) is
