It takes energy to get those electrons up out of their orbitals. It is when they "fall back" and return to their orbitals that they release energy. The energy released will be electromagnetic energy, and if the energy is high enough (but not too high), it will appear as visible light. This is what is happening in a fluorescent tube when it is turned on and emitting light.

What phrases best describes different orbits that electrons can occupy?
energy levels
Do electrons release energy when they move to a higher energy level?
Yes, electrons release energy when they move to a lower energy level. When electrons absorb energy and move to a higher energy level, they are in an excited state. When they return to a lower energy level, they release energy in the form of light or heat.
Why are orbitals of the same energy level degenerate?
Orbitals of the same energy level are degenerate because they have the same amount of energy. In atoms, the energy of an orbital is determined by the principal quantum number n, so orbitals with the same n value have the same energy level. This means that electrons in degenerate orbitals have the same energy and therefore the same potential to interact with the nucleus and other electrons.
When excited electrons return to lower energy levels what is released?
When excited electrons return to lower energy levels, they release energy in the form of photons. This process is known as emission of light or fluorescence. The energy of the emitted photons corresponds to the energy difference between the higher and lower energy levels of the electrons.
Is electrons the only thing arranged in various energy levels or orbitals or are protons arranged the same way?
Protons are not arranged in energy levels or orbitals like electrons. Protons are found in the nucleus of an atom and do not occupy specific energy levels or orbitals. Electrons, on the other hand, are arranged in specific energy levels or orbitals around the nucleus.
How are electrons become excited?
Electrons become excited when they absorb energy, such as through exposure to light or heat. This additional energy causes the electrons to move to a higher energy level, creating an excited state. The electrons will eventually release this energy by returning to their original, lower energy state, emitting light or heat in the process.
When an atom absorbs enough energy electrons move to an orbital?
When an atom absorbs energy, electrons can move to higher energy orbitals further from the nucleus. This process is known as excitation, and it can lead to the temporary promotion of electrons to higher energy levels until they eventually fall back to their original positions, releasing the absorbed energy as light.
Do atoms in the excited state have more electrons than in the ground state?
Yes, because an atom in an excited state will normally give off energy and go to a less-excited state or to its ground state. Some atoms have long-lived excited states and are called "metastable".
How do you tell if an atom is excited in electron configuration?
An excited atom will have electrons that are in higher energy levels than the ground state configuration. This can be observed by seeing electrons in higher energy orbitals or by an electron being promoted to a higher energy level. Spectroscopic techniques can also be used to identify excited atoms.
What makes an elements electrons in an excited state?
An element's electrons can be in an excited state when they absorb energy from an external source, such as heat or light. This added energy causes the electrons to move to higher energy levels further from the nucleus. As the electrons return to their original energy levels, they release this extra energy in the form of light or heat.
What is the relationship between energy levels and orbitals in an atom?
The energy levels in an atom determine the possible locations of electrons, known as orbitals. Each energy level can contain a specific number of orbitals, and electrons fill these orbitals based on their energy levels.
What are visible light and other waves of energy forms of?
broadband blackbody radiation generated by heatnarrow band spectral radiation from excited electrons falling to lower energy atomic orbitals
What is the relationship between orbitals and energy levels in an atom?
In an atom, energy levels represent the different energy states that electrons can occupy. Orbitals are regions within an energy level where electrons are likely to be found. Each energy level can contain multiple orbitals, each with a specific shape and orientation. The higher the energy level, the farther the orbitals are from the nucleus, and the higher the energy of the electrons in those orbitals.
When electrons absorbs energy they exist for a short time higher energy level. These electrons are said to be?
"Excited", or in an "excited state".
How does the electrons become excited?
Electrons become excited when they absorb energy, such as from heat, light, or electricity. This extra energy causes the electrons to move to a higher energy level away from the nucleus of an atom, creating an excited state.
What do the quantum number of electrons represent?
The energy levels and orbitals the electrons are in
