Light Energy increases as you move down the period table among the alkali group.

∙ 14y agoas the electron gets excited to the excited level by gaining certain amount of energy which is equal to the difference in the energies of its initial and final energy states. After a certain period of time the electron jumps back tom lower level by emitting same amount of energy as the difference between the energy of the upper level (the level electron jumped off) and that of lower level. So the energy differences of orbits in an atom and the light emitted by the atom is same

What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
7 Why does a deuterium lamp produce a continuous rather than a line spectrum in the UV?
To answer this question, let's think about the excitation and relaxation processes involved. In the excitation process inside a deuterium lamp, an electrical arc between an oxide coated filament and an electrode excites D2 to D2*. Next, the D2* dissociates into individual D atoms. Let's call these D' and D''. Also, a photon of light is released. For an individual event, the total energy posssessed by D2* is apportioned between the kinetic energies of D', D'', and the photon. The sum of the kinetic energies of D' and D'' can vary from almost zero to the original energy of D2*. If the kinetic energies of D' and D'' are relatively small, the energy of the photon is large, and a shorter wavelength of light is emitted. If the kinetic energies of D' and D'' are relatively large, the energy of the photon is small, and a longer wavelenght of light is emitted. In a population of D2*, a distribution of kinetic energies of D' and D'' will result, allowing for a continuum spectrum to be emitted from the lamp.
Why the speed of beta rays emitted by the same element are different?
because the control of neucles on different electrons is different and we know that beta rays are infact electrons then we can say that the speed of beta rays emitted by the same element is different
When one electron moves from the 4th shell to the 2nd shell in hydrogen is energy absorbed or emitted by the atom?
The energy is absorbed by the electrons because work needs to be done on the electrons to raise them to an excited state. Energy is stored in the electrons while they are in their excited state and would emit energy if they returned to their ground state.
Are the electrons of an atom affected by temperature?
Temperature definitely affects the electrons of an atom, if the temperature is high enough. That is why fires produce light; the light you see from a fire is emitted by excited electrons.
What is the relationship between the light emitted by an atom in the energies of the electrons in the atom?
The more energy levels the electron jumps the more energy the emitted light will have. The more energy you have the shorter wavelength there is.
When an color photon is emitted from some molecule that means molecule jumped from some energy level to lower and emitted it or just one of its atom's electron did?
Either scenario is possible. Some electrons are involved in covalent bonds and have an emission spectrum that depicts that extended commitment. Some electrons are more tightly involved with individual atoms and their emissions are of higher energies.
What are the difference between fluoroscopic and radiography?
In radiography electrons are emitted when x rays fall on the screen, while in fluoroscopy light is emitted.....the electrons emitted in radiography stabilize the silver ions in the film and hence get deposited as metallic silver.The amount of silver deposition is proportional to the amount of electrons liberated which is in turn proportional to the intensity of the x-rays that strike the film.
What are the 2 energies that are emitted by the sun?
1: Light & heat energy 2: Solar energy.
Is synchrotron radiation emitted perpendicular to the circular path of the electrons?
Yes, synchrotron radiation is emitted perpendicular to the circular path of the electrons. This is because the radiation is generated when the electrons are deflected, or accelerated, due to the magnetic field in the synchrotron. The emitted radiation is tangential to the circular path, resulting in a perpendicular radiation pattern.
How are electrons involved in light?
None, light is composed of photons. Light may be emitted or absorbed when electrons undergo transitions between atomic or molecular orbitals, but the light itself does not contain electrons.
Streams of protons and electrons emitted from the Sun produce?
The stream of protons and electrons being emitted from the sun is called the solar wind.
Electrons consist of of ?
Yes , X-rays consist of first moving electrons ,because high voltage between cathode and anode causes the electrons to accelerate toward the anode,When the electrons strike the anode's target area, X-rays are emitted.
Will exposure to red light cause electrons to be emitted from cesium?
No. It will not.
Will exposure to blue light cause electrons to be emitted from cesium?
No
Can an animal see electrons emitted by a cathode ray tube?
no
What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
