When an electron falls from a higher energy level to a lower energy level,the difference in energy is emitted as electromagnetic radiation. Why can it not be emitted as other forms of energy?

(N/A) According to classical electrodynamics,an accelerated charged particle emits energy in the form of electromagnetic waves.
When an electron transitions from a higher energy orbit to a lower energy orbit,it moves closer to the nucleus.
Due to the change in the electrostatic potential energy and the requirement to maintain angular momentum,the electron undergoes a change in its velocity,effectively performing an accelerated motion.
Since the electron is a charged particle,this accelerated motion results in the emission of energy in the form of periodically oscillating electric and magnetic fields,which we observe as electromagnetic radiation.
Other forms of energy,such as mechanical or thermal energy,do not satisfy the fundamental conservation laws and the specific interaction dynamics between the electron's charge and the electromagnetic field during such transitions.
