Ceaseless motion of electron

WebSep 4, 2024 · 10. My textbook says: "Neils Bohr objected to the idea of an electron orbiting a nucleus in a circular orbit. An electron experiences centripetal acceleration and an accelerated charge radiates away energy. So such an orbit would be unstable: the electron would spiral into the nucleus." But why does a charge radiate away energy when … WebDec 19, 2024 · The equation that rules the motion of a free electron in Quantum Mechanics is the Schroedinger equation. iℏ∂ ∂tψ(x, t) = Hψ(x, t) which in its time independent version says ( ψ(x, t) = ψx(x) ⋅ ψt(t)) − ℏ2 2m∇2ψx(x) + V(x)ψx(x) = Eψx(x) As the electron is free, the first part of your reasoning bring you correctly to the ...
