What else can I help you with?
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
What causes an atom to release energy in the form of visible wavelengths of light?
When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.
What happens when an electron in an atom absorbs energy?
When an electron in an atom absorbs a specific "Quantum" of energy, it will jump to the next specific energy level in the atom. It'll then jump back down, and in so doing releasing light and giving off a signature light spectrum for an element.
What happens when electrons go to a higher energy level?
They become less stable and would, therefore, rather be at their original energy level. They often move back down to their original energy level, releasing their excess energy to the environment. Depending on the amount of energy released, a different wave is produced. (e.g. Light wave, Infra-red wave)
What does it mean for an electron to be excited?
The electron starts to move faster.Not a bad try... but to rephrase it- the electron, when excited, jumps to a lower energy orbital and gives off a photon of a certain frequency. this helps it lose the 'excess' energy and re- stabilize.
When the electron emits lights does the electron move up to a higher energy level or down to a lower energy level?
In the Bohr model of the atom, an electron emits a photon when it moves from a higher energy level to a lower energy level.
When electrons jump to a higher energy level they emit or absorb energy?
Electrons are normally in an energy level called the ground state. In the ground state electrons absorb heat energy and then get into the excited state where they release the energy and exert light energy. The light energy can be seen with a spectroscope with a unique bright line emission spectrum.
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.
What must happen to the electron in order for an atom to emit light?
The atom must be subjected to a form of energy which propels the electron(s) to a higher energy level. When the electrons return to their resting state they emit one photon of light at a certain wavelength that our eyes interpret as a color.
What does the atom do when the electron moves from lower to higher energy level?
When an electron moves from a lower to a higher energy level, it absorbs energy and jumps to a higher orbit. This process is known as excitation. The electron can then release this absorbed energy as light when it moves back down to a lower energy level.
What must happen for an atom to go from an excited state to a ground state so color is seen?
An excited electron spontaneously drops back to its ground state, emitting a photon of light as it does so. <><><><><> The same thing happens in the nucleus. An excited nucleus drops down to a lower energy level, releasing a photon.
What is the relationship between the light emitted by an atom and the energies of the electrons in the atom?
Light Energy increases as you move down the period table among the alkali group.
