Answer:
Bohr's model explains the spectral lines of the hydrogen atomic emission spectrum. While the electron of the atom remains in the ground state, its energy in uncharged. When the atom absorbs one or more quanta of energy, the electron moves from the ground state orbit to an excited stats orbit that is further away. Energy levels are designated with the variable n. The ground state is n =1, the first excited state is n = 2, and so on. The energy that is gained by the atom is equal to the difference in energy between the two energy levels. When the atom relaxes back to a lower energy state, it releases energy that is again equal to the difference in energy of the two orbits.
