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?
In the laboratory in a flame test. Electrons are excited to higher energy levels and when they fall back light is emitted. The frequency (colour), v is related to the energy by Plancks equation, E=hv
How can an electron in an atom lose energy to transition from a higher energy level to a lower energy level?
An electron in an atom can lose energy to transition from a higher energy level to a lower energy level by emitting a photon of light. This process is known as emission.
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.
What happens when an electron collides with an atom?
When an electron collides with an atom, it can transfer energy to the atom, causing the atom to become excited or ionized. This can lead to the atom emitting light or undergoing chemical reactions.
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 the

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 brighter the light the more energy is being released, which may alter the arrangement and quantity of electrons in the outer shells within an atom's electron configuration. Dr. Koehler
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.
How can an electron in an atom lose energy to transition from a higher energy level to a lower energy level?
An electron in an atom can lose energy to transition from a higher energy level to a lower energy level by emitting a photon of light. This process is known as emission.
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 an electron has fallen from a higher orbit to a lower orbit. The amount of energy the emitted photon has will equal the energy difference between the initial and final orbits.
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.
