What else can I help you with?
Why is no color emitted from the solid before it is placed into the flame?
Its electrons have not been excited to higher energy levels until after the solid is placed in the flame. The heat causes electrons to be excited and when they fall back down to their ground state, they emit light at a specific wavelength, giving off a specific color of visible light.
What is the definition of excited state electron?
An atom will go into an excited state when the electrons are given extra energy. Then after the electrons have been excited it will eventually go back to ground state producing a light as it returns to its normal state.
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.
How does an excited atom go back to it's ground state?
It must omit a photon of light to lower the excited electron to a lower state. It may require multiple emissions to lower one electron multiple steps or multiple emissions to lower multiple excited electrons. (Incidentally this is why we see a blue sky - excited O2 molecules are emitting blue photons to get back to a ground state)
Why do cations emit colors when heated in a Bunsen burner flame?
Transitions between electronic energy levels release electromagnetic radiation corresponding to the energy difference between the levels. The heat promotes the electrons to the higher level; when they drop back down to the lower level a specific color of light is emitted.
An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
What subatomic particle produces light?
Electrons can produce light when they are "excited," and jump outside their ground state, then hop back, releasing a photon of light.
What emits its own light?
The Sun. And also: when electrons go from excited state back to ground level, the energy that they had transforms into light which is given off.
What is difference between a ground state electrons configuration and an excited state configuration?
In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).
What object emit it's own light?
The Sun. And also: when electrons go from excited state back to ground level, the energy that they had transforms into light which is given off.

An atom absorbs energy as its electron?
An atom absorbs energy as its electron moves to a higher energy level, or an excited state. This process is known as excitation, and the absorbed energy corresponds to the difference in energy levels between the initial and final states.
Does black hold heat?
When a molecule absorbs visible or ultraviolet radiation, electrons in their ground state are promoted to higher states. Through various types of decay, the electrons fall back to their ground states. During this process, some infrared radiation is emitted, which is felt as heat. Black materials emit more infrared radiation because most of the decay of electrons from excited states to ground states involves infrared radiation emission.
What is the definition of excited state electron?
An atom will go into an excited state when the electrons are given extra energy. Then after the electrons have been excited it will eventually go back to ground state producing a light as it returns to its normal state.

What causes the colored flame for each element on the subatomic level?
The heat of the flame gives off energy to the ions. This results in electrons jumping out of their ground state and into their excited state. From a lower subatomic level to a higher one. When the electrons fall back down, the give off a color.
