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.
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".
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
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 makes an elements electrons in an excited state?
Electrons can be excited in an element by supplying energy to the molecule of the elements. Further eletrons get excited in chemical reactions
When one electron moves from the 4th shell to the 2nd shell in hydrogen is energy absorbed or emitted by the atom?
The energy is absorbed by the electrons because work needs to be done on the electrons to raise them to an excited state. Energy is stored in the electrons while they are in their excited state and would emit energy if they returned to their ground state.
When excited electrons return to lower energy levels what is released?
Energy is emitted when an electron moves from a higher energy level to a lower energy level.
Spectral lines produced from the radiant energy emitted from excited atoms are thought to be due to the movements of electrons?
From higher to lower energy levels
One indicator that electrons in atoms are limited to specific energy levels is that?
light emitted from excited atoms occurs only at specific wavelengths
What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
What form of energy emission accompanies the return of an excited electron to its ground state?
What form of energy emission accompanies the return of excited electrons to the ground state?
Why calcium turns to red in the flame test?
Because, due to the absorption of heat energy by the calcium atom in the flame. The electrons in the atom get promoted to a higher energy level, and exist in an unstable excited state. As they are unstable and prefer to be at their normal ground state, the extra energy that the electrons absorbed to be promoted in the first place is emitted in the form of a photon, light. The light emitted from the electrons of the calcium atoms will be at a specific wavelength, which is the red light you see emitted from the flame.

Is energy emitted or absorbed when an electron moves from an excited state to a ground state?
Emitted, and the precise amount of energy that is emitted will depend on what kind of atom, and moving from which excited state. That's how spectrographs can determine what element is present.

How are electrons involved in producing a flame colour?
These colors are generated by excited electrons relaxing back to lower energy levels. Each element has unique energy levels permitted to electrons by quantum mechanics. As an electron drops to a lower level a photon is emitted, carrying away the difference in energy and the higher the energy the shorter its wavelength.
