WebHowever, the atom has to lose energy to do this, and so it releases a photon of the same energy as the one it absorbed (albeit most likely into some other direction from which it was absorbed). This process is called emission because a photon of light is emitted by the atom, again at a very specific wavelength. WebAug 4, 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 the ... http://www.astronomynotes.com/light/s8.htm deterministic view of human nature

What Causes Molecules to Absorb UV and Visible Light

WebEmission spectrums of elements seem to only have frequencies of single-photon emissions. Why is this? For example in hydrogen, when an electorn goes from the 2nd to the 1st energy state, it emits a photon with a wavelength of 122 nm. Why couldn't it also emit two photons, each with a wavelength of 244 nm? WebOct 7, 2024 · (a) Light is emitted when the electron undergoes a transition from an orbit with a higher value of n (at a higher energy) to an orbit with a lower value of n (at lower energy). …

WebDec 13, 2024 · B) The light is emitted when energy from sunlight is absorbed by the atom to excite a neutron into a higher level. C) When the nucleus absorbs sunlight, photons are …

WebContrary to the present-day belief, which suggest that, an atom emits a photon of light when an electron jumps from a high-energy level to a low-energy level... WebFeb 21, 2016 · The electrons in an atom can only occupy certain allowed energy levels. When an electron drops from a higher energy level to a lower one, the excess energy is emitted as a photon of light, with its wavelength dependent on the change in electron energy. The electrons in an atom can only occupy certain allowed energy levels. This was one of the …

WebAug 30, 2004 · Yes, you could transform the mass of a subatomic particle like an electron into light – but that’s not what usually happens when light is emitted from an atom. The energy from the light generally comes from a decrease in the potential or kinetic energy of the electron as it orbits the nucleus. WebTamang sagot sa tanong: Elements emit light of characteristic colors when vaporized. Like sodium atom when heated in the flame will give off yellow color. Which of the following statements explain this? * A. Electrons emit energy and jump to a higher energy level.B. Electrons emit energy and move back to the ground state.C. Electrons absorb energy and …

WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called photoelectrons. In terms of their behavior and their properties, photoelectrons are no ...
