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 happens when an electron in a higher electron cloud drops to a lower energy cloud?
It gains energy in a quantized amount
Why it is considered as the energy of an electron is quantised?
Electrons orbit the nucleus of an atom in specific orbitals, a specific distance from the nucleus of the atom. A specific quanta of energy will knock the electron into a higher orbital. When the electron falls back into the lower orbital, it will give off that same specific quanta of energy. That is why lasers work.
What does incident light that falls on an object do to the electrons in the atoms of an object?
Incident light can excite electrons in the atoms of an object, causing them to move to higher energy levels or even be ejected from the atom as photoelectrons. This can lead to various interactions such as absorption, reflection, or transmission of light depending on the material properties and the wavelength of the incident light.
Why do different atoms produce different colors of light?
Atoms consist of neutrons, protons and electrons. The electrons form 'clouds' around the nuclei of atoms, and in general the nuclei consist of protons and neutrons. The electrons in the outer clouds have more energy than those in the inner clouds. When an electron 'falls' to a lower cloud it a packet of energy is released which might consist of light. Since the energy levels between the clouds vary between atoms the energies released when an electron falls vary from atom to atom. Frequency is equivalent to energy level, and frequency of light is equivalent to colour on the light spectrum.
When an electron falls back to its ground state how much energy is released?
It releases the same amount of energy that it absorbed when it was excited to a higher energy state.
Emission of light from an atoms occurs when an electron?
falls from a higher energy state to a lower energy state.
Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
When an electron falls from n4 to n1, it releases more energy because it is transitioning between high energy states. This higher energy transition corresponds to a shorter wavelength of light being emitted, according to the energy of the photon being inversely proportional to its wavelength. In contrast, when an electron falls from n2 to n1, the energy released is less, resulting in a longer wavelength of light emitted.
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
The energy that is lost when an electron falls to a lower state is emitted as a photon of light. This process is known as photon emission, and the energy of the emitted photon corresponds to the energy difference between the initial and final states of the electron.
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 to the energy of the electron as it falls down the electron transport chain?
pie
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 happens as an electron falls from a higher level to a lower level in an atom?
it falls in 89
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.
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.
When an electron drops from a higher energy state to a lower energy state?
When an electron drops from a higher energy state to a lower energy state, it emits electromagnetic radiation in the form of a photon. This process is known as atomic emission, and the energy of the emitted photon corresponds to the energy difference between the two electron states.
