Question

describe neil bohr's model of an atom

Answer 1

Bohr's Model For Atom :

An atom consist small heavy positively charged new place in the centre and the negatively charged electrons are revolving around it in a circular orbits or shell.

2. As long as an electron revolving in an Orbit, it will not emit or absorb energy.However when an electron absorbs energy it will move away from the nucleus and when it loses energy it will move to some orbits which are nearer to the nucleus.

3. The frequency of radiation absorbed or emitted when transition occurs between two orbits that differ in energy by

◇E = E2 - E1

◇E = hv

4. The angular momentum of an electron in an integral multiple of $\frac{h}{2\pi}$I.e $mvr = \frac{nh}{2\pi}$, where n = 1, 2, 3, 4....

Answer 2

Acc to Bohr,the orbiting electrons were grouped together in shells . Each shell can hold a limited no of elctrons
