Question

How does Bohr’s model of atom explain the stability of the atom ?

Answer 1

Solution:

Neils Bohr explained the stability of atom. He gave a new arrangement of electrons in the atom 1913.


According to Neils Bohr:


1.The Electrons could revolve around the nucleus in only certain orbits or certain energy levels, each Orbit having a different radius.


The electrons which are in orbits close to the nucleus have low energy while those in orbits farther from the nucleus have higher energy.


2. When an electron is revolving in a particular Orbit or  energy level around the nucleus, the electrons does not lose energy even though it has accelerated motion around the nucleus.


Since , The electrons do not lose energy while revolving in certain permitted orbits they do not fall into the nucleus and hence the atom remains stable .

Hope this will help you....

Answer 2

1.) only certain special orbits known as discrete orbits of electrons, are allowed inside the atom

2.) while revolving in discrete orbits the elections do not radiate energy.

3.) These orbits or shells are called energy levels.

4.)These orbits or shells are represented by the letters K, L, M, N,...... Or the numbers, n=1,2,3,4,........
