- A community for students. Which energy transition may take place in the atom if its electron has absorbed a photon? A.n = 5 to n = 1 B.n = 3 to n = 2 C.n = 5 to n = 2 D.n = 1 to n = 3 E.n = 3 to n = 1 Help me!!! if the electron ABSORBS a photon, that means it must GAIN energy. when electrons RELEASE photons, they drop in energy, which is why we see colors in an emission test.

- 1 An electron absorbs the energy of the photon and sends it back out the way it came in. 2  This results in reflection or scattering. 3  An electron cannot absorb the energy of the photon and the photon continues on its path.

Energy Levels of Electrons The electron can gain the energy it needs by absorbing light. If the electron jumps from the second energy level down to the first energy level, it must give off some energy by emitting light. The atom absorbs or emits light in discrete packets called photons, and each photon has a definite energy.

- Electrons with more energy are able to overcome the attraction of the nucleus and inhabit a higher energy level. An electron can store the energy of a photon. Photons are bundles of light energy. When a photon with the right wavelength strikes a pigment, it excites an electron. The electron jumps to a higher energy level. Most of the time, the photoexcited electron only stays at the higher level for a fraction of a second and then drops back down to its ground state.

- Assuming that all of the molecules are in the ground state before excitation, the least energy absorbed in the excitation process (i.e., of the longest wavelength) equals the greatest energy transition in the fluorescence process (i.e., of the shortest wavelength).

Introduction and Pair Production and Annihilation The only requirement is that the gamma-ray photon carries an energy equivalent to the combined rest masses of the electron and positron. If the incident photon has more energy than this then the excess appears as kinetic energy of the electron/positron pair.

What happens to an electron as it absorbs a photon of light? When an atom absorbs a photon its energy is transferred to outer  shell electrons. The result will be the transition of an electron  to a higher energy state.

When an electron moves from a lower to a higher energy level, the electron does what? Answer is (c) i.e. absorbs a quantum of energy. The word quantum means a fixed amount of energy. Electron always absorbs a fixed quantity of energy so that it can jump from lower energy level to higher energy level. At the same time electron will lose that same quantity of energy in form of radiation to come back to the lower energy level. gpina_9 · 8 years ago.

- l = hc/E. A photon with an energy of 10.2 eV has a wavelength of 1.21 x 10 -7 m, in the ultraviolet part of the spectrum. So when an electron wants to jump from n = 1 to n = 2, it must absorb a photon of ultraviolet light. When an electron drops from n = 2 to n = 1, it emits a photon of ultraviolet light.

Electrons, photons, and the photo-electric effect Energy of a photon : E = hf. The photoelectric effect works like this. If you shine light of high enough energy on to a metal, electrons will be emitted from the metal. Light below a certain threshold frequency, no matter how intense, will not cause any electrons to be emitted.

Absorption spectroscopy Radiation is more likely to be absorbed at frequencies that match the energy difference between two quantum mechanical states of the molecules. The absorption that occurs due to a transition between two states is referred to as an absorption line and a spectrum is typically composed of many lines.

Early Photoelectric Effect Data The minimum energy required to eject an electron from the surface is called the photoelectric work function. The threshold for this element corresponds to a wavelength of 683 nm. Using this wavelength in the Planck relationship gives a photon energy of 1.82 eV.hotons: The Quanta of Light. According to the Planck hypothesis, all electromagnetic radiation is quantized and occurs in finite bundles of energy which we call photons. The quantum of energy for a photon is not Planck's constant h itself, but the product of h and the frequency.

- These electrons can then leave with a kinetic energy equal to the incident photon energy minus the 'work function' which was the energy required to ionise the atom. The work function is the energy required to remove the electron from the surface of a material.

- For photons incident upon matter there is a chance that scattering will occur with the final photon having the same energy as the incident photon. This violates conservation of momentum and energy if we think of them as the same photon being bounced off of the atom.

- Thus, the photons absorbed or emitted by a sample of the atom in question are a direct probe of. the energy difference between quantum states of that atom. Again, the behavior of electrons within molecules can be probed in pretty much the same. manner. In the case of emissions from excited atoms, observing emitted photons of multiple wavelengths. implies many quantum states may be involved in producing the spectrum.

Under What Circumstances Can an Atom Emit a Photon? Quick Answer. Atoms emit a photon when an electron falls from a high-energy state to a low-energy state. The conditions under which this process occurs happen in two ways. According to the Cornell Center for Materials Research, electrons either absorb the energy from a photon and jump to a higher energy level or a photon collides with an electron that is already in an excited state.

- The amount of energy an atom can absorb depends on the energy separation of the electronic levels of the atom. If light of frequency, (, is incident on the atom, the atom will absorb this light only if the energy of a photon of this light () equals the energy difference between two electronic levels of the atom.

- The absorption of a photon of energy by a fluorophore, which occurs due to an interaction of the oscillating electric field vector of the light wave with charges (electrons) in the molecule, is an all or none phenomenon and can only occur with incident light of specific wavelengths known as absorption bands.

- When an electron absorbs a photon of light, it gains energy. This is quantized. When an electron gains energy, it moves to a higher energy level. Thus giving the equation hf=m … cv. Therefore, as more energy is given to the electron, it gets 'excited' and maintains the energy by moving to a higher energy leve.

Types of Astronomical Spectra Electron transitions in the Bohr model of the Hydrogen atom. As electrons jump down to the n = 2 orbit, they emit photons of specific frequency (hence colour) that can be seen as emission lines in the visible part of the em spectrum. This visible set of lines is called the Balmer series.

- The photon the electron ejects has an amount of energy that corresponds to the energy state it's jumping from to the one it's falling to, we express this energy in terms of that photon's wavelength. So, when an electron falls from n=3 to n=2, it ejects a photon with a wavelength of about 653 nanometers. That photon eventually travels from the nebula to Earth, where it hits your eye or a telescope or whatever, and appears red. This is reason most emission nebulae look red.
