Explain Bohr’s Atomic Model.
by

1 Answer

Answer :

Ans : Bohr’s Atomic Model : 1. Bohr proposed that electrons move only in certain energy level & does not radiate energy continuously. Hence will not fall in nucleus. 2. Atoms radiate energy as light in discrete quantity called quanta. 3. Atoms only radiate energy when change their energy level. This energy is directly proportional to the frequency of radiation. ΔE = E2 – E1 = hv
