Electron centripetal acceleration

    hi experts
    electrons certainly have centripetal acceleration - and we learned that accelerated particles do emit EM waves - than does electron radiate while revolving around nucleus?

    Welcome to PhysicsForums, wasi-uz-zaman!

    Electrons do not behave in the manner you describe, and they do not radiate while occupying an orbital. The idea that they did was recognized long ago as leading to serious theoretical problems.

    The electron has no centripetal acceleration. It obeys no law from classical physics.

    OK then why electron have angular momentum

    Scientists do not know yet.

    As far as they know, "It just does."
