Which mechanism causes stable electron orbits avoiding continuous emission in the presence of an accelerating electron near an atom's nucleus?

A)Quantization of angular momentum
B)Heisenberg uncertainty principle
C)Electromagnetic wave interference
D)Electron-positron annihilation

💡 Explanation

Stable orbits occur because electrons occupy quantized energy levels corresponding to specific angular momentum values, undergoing transitions only with specific energy exchange, rather than radiating continuously; therefore, quantization avoids continuous energy loss, which is central to atomic stability instead of others.
