| . An atom consists of a positively charged sphere with electrons embedded in it. | . An atom consists of a positively charged particles concentrated at the center known as the nucleus.
. The size of the nucleus is very small as compared to the size of the atom. . The electron revolve around the nucleus in well – defined orbits. |
. There are only certain orbits know as discrete orbits inside the atom in which electrons revolve around the nucleus. Electrons do not radiate energy while revolving. |
