Emissin of light from an atom occurs when an electron what?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
Why does an electron produce colors when exerting energy?
When an elctron is excited (has energy) it is extremely unstable, so it falls back to its previous energy level, and when it does this it releases energy, and this energy is viewed as wavelengths of light. So the color depends on the amount of energy the atom releases when it falls back to its lower energy level.
What has to happen before you can move to a new energy level in the electron cloud?
When an electron falls from a higher to lower energy level, it emits a photon. Atom will emit only light with a wavelength (color).
How is the light of an emission spectrum of an element produced?
Basically, energy is emitted when an electron falls from a higher energy level to a lower energy level. Such energy is emitted as electromagnetic waves, which in certain cases can be visible light.
What happened to the energyof an electron as it goes farther from the nucleus?
if an electron gains enough energy it jumps to a higher energy level. when this happens the atom is in an "excited" state.
What happens as an electron falls from a higher level to a lower level in an atom?
it falls in 89
What happens when a electron moves to higher energy level?
The electron gains energy.
What happens when an electron moves to a higher level?
The electron gains energy.
What happens when ann electron moves to a higher energy level?
It falls back to its ground state, emitting light of a particular wavelength and color.
Which principal energy level will contain electrons with the lowest energy is what?
First energy level bc as the electron falls from high to low it emitts energy
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
How do you generate light?
Light is generated when photons are emitted from an atom. This occurs when an electron on one energy level of an atom falls to a lower energy level.
The line emission spectrum of an atom is caused by the energies released when electrons?
The line emission spectrum of an atom is caused by the energies released when electrons fall from high energy level. It goes down to a low energy level and the extra energy it had from higher level is released as light.
Emissin of light from an atom occurs when an electron what?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
What happens when an electron moves higher energy level?
It gains energy in a quantity amount or whatever it says
What happens when an electron moves from a high energy level to a lower one?
It absorbs light
Why does an electron produce colors when exerting energy?
When an elctron is excited (has energy) it is extremely unstable, so it falls back to its previous energy level, and when it does this it releases energy, and this energy is viewed as wavelengths of light. So the color depends on the amount of energy the atom releases when it falls back to its lower energy level.
