Question

Quizplus · Accepted Answer

Excitation is the process of adding energy to an atom, which can cause one or more of its electrons to transition to a higher energy level or become less tightly bound to the nucleus. This can happen through various mechanisms, such as absorption of photons or collisions with other particles. Doppler broadening and collisional broadening refer to effects on spectral lines due to motion and collisions of atoms, respectively. A red shift refers to the apparent shift of spectral lines towards longer wavelengths, often observed in astronomical objects moving away from us. Quantum mechanics is a broad field that encompasses the study of the behavior and properties of matter and energy on the atomic and subatomic scale, and is not specifically related to the process of making an electron less tightly bound to an atom's nucleus.
