What happens to electrons that are closer to the nucleus during bremsstrahlung interaction?

During bremsstrahlung interaction, when electrons come close to the nucleus of an atom, they experience a significant electrostatic attraction due to the positive charge of the nucleus. This interaction causes the electrons to slow down as they approach the nucleus because they are essentially being drawn in by this positive charge. As a result of this deceleration, the electrons lose some of their kinetic energy. The energy that is lost is emitted in the form of X-ray photons, which is the fundamental principle behind bremsstrahlung radiation.

While options regarding gaining energy, being repelled, or becoming free electrons may seem plausible, they do not accurately describe what occurs during bremsstrahlung. The primary effect observed is the deceleration of electrons and the emission of X-rays due to energy loss as they interact with the nucleus, confirming that they slow down and lose more energy as they approach the nucleus during this process.
