Why do ions have different colors in a flame test?
When a metallic ion is heated in a flame test, the heat (energy) causes an electron to be exicted to a higher energy state. When this electron returns to a lower energy state, energy is emitted as visible light. Depending on how much energy is released when the electron returns from the higher to lower energy state will determine what color the flame will be.
What colour does barium give off when put into a flame?
Barium ions give off a green colour when heated in a flame.

What colour is the flame when the airport is open and when the airport is closed on a Bunsen Burner?
its a orange colour when closed and a blue colour when is open
Is it sufficient to identify a cation on a flame test?
It is not suffiecient to identify a cation only on a flame test.æ You must also identify the color of the flame which corresponds to a certain element.
Is flame coloration a test for the metallic ion or for the nitrate ion?
Flame coloration is a test for the metallic ion. When a metallic ion is heated in a flame, it absorbs energy and then emits light at specific wavelengths, producing characteristic colors. The nitrate ion itself does not directly contribute to the color of the flame test.
What colour flame does calcium produce in a flame test?

What colour flame do you get when you burn sodium?
You get and orange - yellow colour.
What is the flame colour of californium?
I suppose that the flame test was not applied to californium.
Which colour flame on Bunsen burner burns cleaner?
The blue flame.
What effects would you expect on the flame colors if these compounds were chlorides instead of nitrates?
If the compounds were chlorides instead of nitrates, you would likely see a different color flame due to the different metal cations present. For example, potassium chloride would produce a lilac flame, while strontium chloride would produce a red flame. Each metal cation emits a characteristic color when ions are heated.
Which is the Coldest colour of a flame?
Blue?
What flame colour is the coldest?
yellow
Why does the anion not play a role in the color of a flame in a flame test?
Anions do not play a role in the color of a flame in a flame test because they are not visible as the energy gap do not correspond to that of a visible photon. Flame tests are only applicable to cations.
