Why does sodium vapor emit only certain frequencies of visible light?
It is because the electrons surrounding an atom, say sodium, can only exist at certain energy levels. When a photon (packet of light energy) hits an orbiting electron it only gives energy to that electron if the energy of the photon is exactly enough to move the electron to a higher energy level, if not it doesn't effect the electron. As the energy of a photon is directly proportional to the it wavelength, only certain wavelengths affect an atom's electrons. When they do effect the electrons the photon is absorbed, giving the absorption spectrum. Emission spectra are the reverse of this process, when an electron cascades back down to its lowest possible energy state after this photon interaction it gives out certain frequencies of light. The energy of this light will be equal to the energy absorbed, so the photons emitted will be equal to the photons absorbed which is why emission spectra look like the inverse of an absorption spectrum.
When an electron drops to a lower energy level what is the energy of the photon released?
The energy of the photon is the same as the energy lost by the electron
When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?
electron lost 3.6 x 10-19 -barbie=]
What electron transition represents a gain of energy?
All transitions in which electrons move from a lower to a higher level require a gain of energy. example: 2nd to 3rd shell
What state does an electron move to its ground state from in a gaseous atom in order for a photon to be emitted?
In a transition to ground state, a photon is radiated away. It carries off the energy to make a transition to ground state possible. As soon as it is created, the photon is off to the races. It travels away at the speed of light (for the medium in which it is moving).
What happens when photon is absorbed by atom?
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.
What does the electron produce when they change energy levels?
a photon is emitted or absorbed
An electron gains 5.5 x 10-16 J of energy when a photon is absorbed What is the frequency of the photon that is absorbed?
8.3 x 1017 Hz
When an electron drops from a higher energy state to a lower energy state?
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
What happens to electrons when pigments in photo-systems 2 absorb light?
Light or photons are little packets of energy. When this energy is absorbed by an electron it boots the electrons energy and the electron jumps to a higher orbital shell position (which must be vacant of its electron). The electron can only do this when the energy needed for the jump and the energy in the incoming photon match. Thus specific colours of light are absorbed depending on the element present.
When an electron moves up to a higher orbit a quantum of light energy is absorbed. This quantum of light energy is also known as?
photon
When an electron moves up to a higher orbit a quantum of light energy is absorbed this quantum of light energy is also known as?
photon
When an electron moves up to a higher orbit a quantum of light energy is absorbed This quantum of light energy is also known as a?
Photon
When an electron drops to a lower energy level what is the energy of a photon released?
The energy of the photon is the same as the energy lost by the electron
When does an atom produce light?
When light (a photon) collides with an atom, the energy contained by it is absorbed and it bumps one of the electrons orbiting it up to a higher energy level. ( there are several energy levels, think of it as stories of a building) Later when the electron falls down 1 or more energy levels, The energy is released as another photon. If the electron drops down to the original energy level, the same intensity photon is released as was absorbed. If it drops down in 2 or more steps, several photons will be released of varying intensity, depending on the amount of levels dropped.
When an electron falls from a higher energy level to a lower energy energy level how is the energy released?
The energy is released as electromagetic energy and each transition in each atom has its own wavelength for the light emitted.
