Question

State the postulates of Bohr's Model of atom.

Answer 1

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

Answer 2

Postulates of Bohr's model of atom:-

1. The electrons revolve around the nucleus in a fixed circular path called orbits or shells.

2. An electron revolving in a particular orbit has a fixed energy.

3. These orbits or shells are known as energy levels. Energy levels in an atom are shown in figure below.

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