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
When the electrons of an excited atom return to a lower energy state the energy emitted can result in the production of what?
When the electrons of an excited atom return to a lower energy state, the energy emitted can result in the production of light, in the form of photons. This process is known as emission spectroscopy and is used in various analytical techniques to identify elements or compounds based on their characteristic emission spectra.
Why cant an atom in the ground state produce emission lines?
An atom in the ground state does not have any electrons excited to higher energy levels. Without these excited electrons transitioning back to lower energy levels, there is no emission of photons with specific wavelengths that correspond to emission lines.
What does a hydrogen atom transitioning from the 2nd to the 1st excited state produce?
A hydrogen atom transitioning from the 2nd to the 1st excited state produces a photon of ultraviolet light. This ultraviolet light has a specific wavelength corresponding to the energy difference between the two states.
According to Bohr's theory what would an excited atom do?
Excited atoms, according to Bohr's theory, would release the excess energy by emitting photons of specific frequencies as they return to lower energy states. This emission of light is known as atomic emission.
What does a photon do in the process of light absorption and emission?
A photon is a tiny particle of light that is absorbed by an atom or molecule during the process of light absorption. This absorption causes the atom or molecule to become excited, leading to the emission of a new photon when the atom or molecule returns to its original state.
What does the change of an atom from an excited state to the ground state always require?
An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.

What happens when a hydrogen atom changes from the excited state to the ground state?
When a hydrogen atom transitions from an excited state to the ground state, it releases energy in the form of a photon. The photon emitted corresponds to the difference in energy between the two states, typically in the form of visible light, ultraviolet, or infrared radiation. This process is known as spontaneous emission or photon emission.
The lines in the bright line spectrum of an atom are due to what?
The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.
Why does stimulated emission occur (your answer should include an explanation of probability)?
Stimulated emission occurs when an incoming photon interacts with an excited atom, causing it to emit a second photon that is identical in frequency, phase, and direction. The probability of stimulated emission is higher when the atom is already in an excited state and encounters an incoming photon with the same energy level, which promotes the emission process. This process amplifies the intensity of the light signal and is the basis of operation for lasers.
Is the emission of electromagnetic radiation by an excited atom a wave or particle theory?
wave theory of light
Principle of Spontaneous emission and stimulated emission?
Spontaneous emission is the process where an atom or molecule transitions from a higher energy state to a lower energy state, emitting a photon in the process without any external stimulation. Stimulated emission occurs when an incoming photon triggers an atom or molecule already in an excited state to emit a second photon that has the same wavelength, phase, and direction as the incoming photon, resulting in the amplification of light.
