There is also a maximum energy that each … WebLight is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles, called light photons, are the most basic units of light. (For more information, see How Light Works .) Atoms release light photons when their electrons become excited.
Web4 de ago. de 2024 · The atom has energy levels, and if the photon energy coincides (within a small Δ E, the width of the energy level) with the transition energy of kicking an electron to an empty energy level, then the atom can absorb the photon (not the electron). So the answer to "why", above, is "because the photon has the appropriate energy to transfer … WebThe collisions involving the Hg atoms cause electrons to be removed from the Hg atom (ionization). The electrons become free electrons. Ionization does not emit photons. …
