Question

Write three significant features of Bohr’s Model of atom.

Answer 1

   -  Electrons revolve in discrete orbits called shells.
    -  Electrons revolve in their orbits without radiating energy. Within a particular orbit, the energy of an electron is constant. This is why orbits are called stationary orbits or stationary shells.
     - Orbits or shells are also known as energy levels.
  

Answer 2

---electrons revolve around discrete orbits called shells

---they revolve around the orbit without radiating energy.in an orbit it remains because of which it is called as stationary orbits

---the orbits are also known as energy levels

---they are represented by constants like ,K,L,M,N etc
