electrons certainly have centripetal acceleration - and we learned that accelerated particles do emit EM waves - than does electron radiate while revolving around nucleus?
wasi-uz-zaman said:OK then why electron have angular momentum
Electron centripetal acceleration is the acceleration experienced by an electron as it moves in a circular path around a central point, caused by the inward force of an electric or magnetic field.
Electron centripetal acceleration can be calculated by using the formula a = v^2/r, where "a" is the acceleration, "v" is the velocity of the electron, and "r" is the radius of the circular path.
The two main factors that affect electron centripetal acceleration are the velocity of the electron and the radius of the circular path. Additionally, the strength of the electric or magnetic field also plays a role in determining the acceleration.
In the Bohr model of the atom, electrons move in circular orbits around the nucleus. This means that they experience centripetal acceleration due to the inward force of the nucleus. This helps to explain the stability of atoms, as the centripetal acceleration keeps the electrons in their orbits.
Electron centripetal acceleration and electron velocity are related, but they are not the same thing. Velocity refers to the speed and direction of an electron's motion, while centripetal acceleration refers to the change in velocity caused by the centripetal force acting on the electron. In other words, velocity tells us how fast the electron is moving, while centripetal acceleration tells us how quickly the electron is changing its velocity in a circular path.
