When an atom emits light, an electron in the atom transitions from a higher energy state to a lower energy state. This transition releases energy in the form of a photon of light. The atom remains the same element before and after emitting light.

An excited atom can lose energy by?
An excited atom can lose energy by emitting a photon of light, a process known as spontaneous emission. This photon carries away the excess energy, allowing the atom to return to a lower energy state.
When is the characteristic bright-line spectrum of an atom produced?
The characteristic bright-line spectrum of an atom is produced when electrons in the atom transition from higher energy levels to lower energy levels, emitting photons of specific energies. This occurs when the atom is excited by either heat, light, or electricity causing the electrons to move to higher energy levels and then return to their original state, emitting the characteristic wavelengths of light that we observe as the bright-line spectrum.
What radioactive atoms spontaneously do?
Radioactive atoms spontaneously decay, emitting particles or energy in the process. This decay can result in the transformation of the atom into a different element or isotope to achieve a more stable state.
Did cl change oxidation number tue or false?
True. A change in oxidation number occurs when there is a transfer of electrons from one atom to another, leading to a change in the oxidation state of an element in a chemical compound.
Emission of light from an atom occurs when the electron?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
An excited atom can lose energy by?
An excited atom can lose energy by emitting a photon of light, a process known as spontaneous emission. This photon carries away the excess energy, allowing the atom to return to a lower energy state.
Do atom or molecules change identity when a change of state occurs?
yes
What is the energy change that occurs when an atom gains electrons called?
The energy change that occurs when an atom gains electrons is called electron affinity. It represents the amount of energy released when an atom accepts an electron to form a negative ion.
When is the characteristic bright-line spectrum of an atom produced?
The characteristic bright-line spectrum of an atom is produced when electrons in the atom transition from higher energy levels to lower energy levels, emitting photons of specific energies. This occurs when the atom is excited by either heat, light, or electricity causing the electrons to move to higher energy levels and then return to their original state, emitting the characteristic wavelengths of light that we observe as the bright-line spectrum.
What is the energy change that occurs when an atom loses electrons called?
ionization energy
How does the electron configuration of an atom relate to the amount of light emitted during an energy releasing event?
The electron configuration of an atom determines the energy levels of its electrons. When an energy-releasing event occurs, electrons can transition between these energy levels, emitting light with a specific wavelength corresponding to the energy difference between the levels. This emitted light is characteristic of the element and can be used to identify it.
Can atoms change energy levels?
Yes, atoms can change energy levels by absorbing or emitting energy in the form of light or heat. This process is known as electronic transitions. When an atom absorbs energy, its electrons move to higher energy levels, and when it emits energy, its electrons move to lower energy levels.
Absorption of light by atoms of an element occurs when photons are?
Absorption of light by atoms of an element occurs when photons of light with energy levels matching the energy levels of the electrons in the atom are absorbed. This causes the electrons to move to higher energy levels, and the atom becomes excited, leading to the absorption of light.
Sketch an atom emitting light. Does the electron end up in a higher or lower orbit. Repeat for an atom absorbing light?
When an atom emits light, the electron transitions from a higher energy level to a lower energy level within the atom, releasing energy in the form of light. The emitted light has a wavelength corresponding to the energy difference between the two energy levels involved. When an atom absorbs light, the electron absorbs the energy of the incoming photon and jumps to a higher energy level within the atom, moving to a more excited state.
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.
What atom glows with electricity?
A neon atom glows when electricity passes through it, creating the characteristic neon light commonly seen in signs. This is due to the energy released as the electrons in the neon atoms jump to higher energy levels and then return to their ground state, emitting light in the process.
What radioactive atoms spontaneously do?
Radioactive atoms spontaneously decay, emitting particles or energy in the process. This decay can result in the transformation of the atom into a different element or isotope to achieve a more stable state.
