What particles in an atom are light particles?
Electrons are the lighter particles of an atom. If you are referring to the phenomena of light in electromagnetic radiation the particles are called photons. They are not part of an atom as such but can be emitted or absorbed by atoms under certain circumstances.
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.
Is energy is conserved when an atom emits a photon of light?
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
What happens to the electrons after absorbing energy from light?
After absorbing energy from light, electrons in an atom can move to higher energy levels or be released from the atom altogether in a process called photoemission.
How can an atom of size 1angstrom can absorb a photon of 5000 wavelength?
I presume you asking, "How can an atom of size about 1 angstrom absorb a photon whose wavelength is 5000 angstroms? Wouldn't the photon be too large for that atom?" The paradox is resolved in this way: the instant you start to discuss electro-magnetic radiation as a photon instead of a transverse electro-magnetic wave, then you negate the wave-length aspect of the light. Instead, you view light as a collection of photons -- particles whose "size" (if that word has meaning) is point-like -- with a specific energy instead of specific wavelength. A photon is NOT a snake-like wave, vibrating like a rubber band, with a length at least that of its wave-length, as it moves through a medium. A photon is a point particle with a specific energy. You can describe light as a EM wave with a wave-length OR as a collection of point particles. You can NOT do both at the same time. Light exhibits the characteristics of one OR the other, but NEVER both.

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.

Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.

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.
If a certain fluorescing dye was2 emit a photon with an energy of 4.1x10-19J would this a suitable candidate for a light stick would this photon then be the same as the photon of a hydrogen atom?
no
What is the light particle called that an atom gains energy from?
The light particle that an atom gains energy from is called a photon. When an atom absorbs a photon, it can become excited, meaning one of its electrons moves to a higher energy level. This process is fundamental in various phenomena, including photosynthesis and the emission of light from fluorescent materials.
A sentence for photon?
A photon is a sub atomic particle is a single enery packet of light As it has no mass it can travel at the speed of light (since it is light) and are created when an electron makes a quantum leap inside an atom.
How do atom put off ultraviolet light?
An atom could put off ultraviolet light if it was excited by ultraviolet light at the appropriate energy level. Atoms emit light when they are hit with the exact energy of photon to promote electrons to higher orbitals. The light is emitted as the electron drops back to its ground state.
What is happening in an atom when light is given off?
light is given off by an atom when and electron moves from one shell to a lower shell and a specific amount of energy is released in the process (known as a photon). If the wavelength of the released photon are in the spectrum of visible light, we will see it as a specific color based on the wavelength of the photon.
How can an atom of size 1angstrom can absorb a photon of 5000 wavelength?
