← ScienceWhich 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.
