Bohr’s Model of Atom
- According to Neil’s Bohr the electrons could revolve around the nucleus in only certain orbits known as discrete orbits of electrons, each orbit having different radii.
- When an electron is revolving in a particular orbit around the nucleus the electron does not radiate energy.
- Bohr’s model of an atom can be described as follows:-
- An atom is made up of three sub-atomic particles – protons, electrons, neutrons.
- The protons and neutrons are located in a small nucleus in the centre of the atom.
- The electrons revolve around the nucleus rapidly in fixed circular paths called energy levels or shells.
- There is limit in the number of electrons that each shell can hold. It is given by the formula 2n2, where n = orbit number or energy level index.
- Each energy level is associated with a fixed amount of energy.
- There is no change in the energy of the electrons as long as they keep revolving in the same energy level, and the atom remains stable.
