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.

Why lithium flame give red color?
Lithium flame gives a lilac colour when ignited.
Why does barium give a green flame test?
The heat of the flame excites the metals ions, causing them to emit visible light. The characteristic emission spectra can be used to differentiate between some elements.SO the characteristic emission spectra of Barium contains wavelengths corresponding to green color.
What color flame would cupric nitrate produce?
The flame color would be green.
What flame color does aluminum nitrate produce?
This compound will not produce a flame as Aluminum, which is the element that controls whether photons(flame color) are released or not.
What evidence is there that the characteristic color observed for each compound is due to the metal ion in each case?
The evidence is shown because each metal ion gave off a different flame color. If you were to do additional testing, you could use different salts of the same metal and see if the flame color is the same. Ps: Im doing this lab right now.
What is happening in flame test lab?
Due to electron transitions in atoms some chemical elements emit a characteristic colored flame.
What does it mean if no color is produced in a flame test?
The elements contained in this molecule are not able to give a color in the flame.
Is the flame test a qualitative or quantitative test for the identity of an unknown?
just looking at the color of the flame --- qualitative
Why do the flame change colours according to the different element in flame test?
it has something to do with the chemical composition of the elements.
How does a flame test help to identify inorganic substances?
The color of the flame is indicative of the constituent elements.
What do flame test show about the structure of atoms?
The flame test is only for qualitative identification of some chemical elements.
Why did each compound produce a flame of a different color?
Different elements have different emission spectra, meaning that if the electrons in an atom are excited, they will release that energy in different color of light. The flame color depends on the elements in the compound.
Why lithium flame give red color?
Lithium flame gives a lilac colour when ignited.
What color does lead burn?
Lead burns with a bluish-white flame when ignited. Flame tests use analysis of flame color to detect the presence of particular elements within a compound.
What does the flame test tell you about chemicals?
With the flame test we can identify some chemical elements; see the link to Wikipedia, for ex.
How can you distinguish a characteristic property of solubility?
densty, boiling point, solute solubility, flammability, and color in flame.
When a metal is heated in a flame the flame has a distinctive color the information was eventually extended to the study of stars because?
Because the color spectra of stars indicate which elements are present.
