Energy Levels

[annikaying]

I was wondering if when an electron drops two energy levels does that mean that two photons are released or is it just a photon with more energy?

[Vanessa Chuang 4F]

I think that electrons generally only drop one energy level at a time so they would emit one photon when they drop the first level and then emit a second photon when they drop the second level.
I'm not 100% sure about this though so if anyone knows for sure, please correct me if I'm wrong

I believe that 1 photon is always released per energy change. This can be observed by the fact that light of just ONE frequency can cause an electron to jump 2 energy levels.

When an electron drops two levels, it is not that two photons are emitted, but that the one photon that is emitted has more energy that if the electron only dropped one level.

Electrons CAN jump two energy levels and even more. Think about the Lyman Series, comprised of all the emissions that are involved with jumps from or to n=1. There are several emissions in the series, one line for the jump from n=2 to n=1, another line (with more energy) for the jump from n=3 to n=1 (and so on). Since there is a distinct line for each, and each line represents a photon with a certain wavelength and therefore a certain energy, only one photon is released for each of these jumps.

I believe that the more energy levels an electron drops, the greater the change in the kinetic energy is. I does not have to drop one energy level at a time.

One photon would be emitted with each successive drop in energy level.

When looking at energy levels, is there a direct correspondence of 1 photon -> 1 energy level? wouldn't it depend on the intensity of a photon, or is the intensity the same for all photons, and thus a constant relationship between photons and energy level?

When an electron drops two energy levels, only one photon will be released, but the photon would have more energy than that released from an electron dropping one energy level. In the photoelectric effect, electrons exhibit properties of one sort of particles called photons. When thinking this way, it is much easier to understand that one electron could only cause the emission of one photon.
