# Bohr's atomic model [duplicate]

Why don't the electrons revolving around the nucleus in the Bohr's atomic model lose energy? I mean don't they accelerate because of which they should emit radiations. I don't get this concept. can someone help me out with this?

• The difficulty with the proposed duplicates is that most of the answer don't really address the misconception here. That is, they don't talk about the importance of the vanishing second derivative of $\langle X \rangle$ with respect to time (mine is as guilty as any other in that regard). – dmckee Sep 6 '15 at 20:51
