Question

State the postulates of Bohr's Model of Atom.

Answer 1

Postulates of BOHR'S model of an atom are:

1. An atom is made up of three particles- electrons, protons, and neutrons.

2.The protons and neutrons are located in a small nucleus at the center of the atom.

3.The electrons revolve rapidly round the nucleus in fixed circular paths called energy levels or shells

4. There is a limit to the no. of electrons which each energy level could hold.

5. Each energy level is associated with a fixed amount of energy.

6. There is no change in the energy of electrons as long as they keep revolving in the same energy level, and the atoms remain stable

Answer 2

the postulates of Bohr's Model of Atom are
---------------------------------------------------------------------------------------
1)electrons revolve around the nucleus in a  circular path called orbits

2)when the electrons are in same energy level there is no change in energy

3)when the electron jumps from lower level to upper level it gains energy but when it jumps from higher to lower level it looses energy

4)only those shells are possible around the nucleus whose angular momentum is a integral multiple of h/2π
