Question
What are three postulates given by Bohr's model of the hydrogen atom?Explain them fully and clearly
Open in App
Solution
1. An atom has a number of stable orbits in which an electron can reside without the emission of radiant energy. Each orbit corresponds, to a certain energy level.
2. An electron may jump spontaneously from one orbit (energy level E1) to the other orbit (energy level E2) (E2 > E1); then the energy change AE in the electron jump is given by Planck’s equation. ∆E = E2-E1 = hv
Where h = Planck’s constant.
And v = frequency of light emitted.
3. The motion of an electron in a circular orbit is restricted in such a manner that its angular momentum is an integral multiple of h/2π.
