When metal is heated the light emitted is because it gains energy as they return to lower energy levels?

Just the opposite. As an electron returns to a lower energy level, it emits a packet (quantum) of energy that may be a visible photon.

To say that energy levels in an atom are discrete is to say the energy levels are well defined and?
That because only certain photons are emitted, we know that only certain energy changes are occurring.
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.
What does the electron produce when they change energy levels?
a photon is emitted or absorbed
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.
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.

What is the relationship between the light emitted by an atom in the energies of the electrons in the atom?
The more energy levels the electron jumps the more energy the emitted light will have. The more energy you have the shorter wavelength there is.
How does the energy of a photon compare in difference in energy levels of the atom from which it is emitted?
The energy of a Photon is equal to the difference in the energy level of the Atom that it came from.

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.
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.
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.
Is an element's flame color a chemical characteristic?
The color of the light emitted by an element heated within a flame is a physical characteristic, but this particular physical characteristic is itself determined by a chemical characteristic: the distribution of electron energy levels within the element.
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
What was The quantum theory of energy levels within atoms was aided by?
The quantum theory of energy levels within atoms was aided by the emission spectrum. When excited with light, different elements emitted photons of different frequencies. The frequencies were different because the energy difference from excited to low energy state was different depending on the element.
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
