1.	Q3. (a) Give the main features of Bohr's atomic model.
Answer» a)Features of Bohr’s Models :(i)Electrons revolve in certain permitted orbits which are associated with fixed amount of energy. So they are called energy levels (K, L, M, N).(ii) As long as electron revolves in the same energy level, they do not radiate energy.(iii)The energy of orbit closest to nucleus is lowest and farthest away is highest.(iv)When we supply energy to electron, it goes to higher energy level and when it comes back to lower level it radiates energy. tqu The Bohr model has the following features: 1) There is a nucleus (this was Rutherford's discovery).2) The electrons move about the nucleus in "stationary states" which are stable, that is, NOT radiating energy.3) When an electron moves from one state to another, the energy lost or gained is done so ONLY in very specific amounts of energy, not just any old amount.4) Each line in a spectrum is produced when an electron moves from one stationary state to another.

The Bohr model has the following features:

1) There is a nucleus (this was Rutherford's discovery).2) The electrons move about the nucleus in "stationary states" which are stable, that is, NOT radiating energy.3) When an electron moves from one state to another, the energy lost or gained is done so ONLY in very specific amounts of energy, not just any old amount.4) Each line in a spectrum is produced when an electron moves from one stationary state to another.
