hi, the metal salts used in the flame tests are the same as those used to make fireworks. when the metal salt is heated the electrons get excited and jump to a higher level. As they get less excited they drop back down a level and the energy they lose is lost as light. This is what we see as the colour.

What color does beryllium produce in fireworks?
to the best of my knowledge beryllium is not used in pyrotechnics at all it is quite hideously toxic, and it is one of those metals that imparts no particular coloration that is visible to the naked eye in flame/fluorescence tests
How do impurities affect the outcome of the flame tests?
The result can be erroneous.
When doing flame tests Li Cl and K Cl both contain Cl so what makes the flame tests different colors?
The flame tests are different because they contain different metal cations. Since the metals were the variable that you changed, you know that can be the only reason why the flames would be different colors.
How is a diagnosis of lice infestation confirmed?
Blood tests or other laboratory tests are not useful in diagnosing lice infestations.
What elements produce red color in fireworks?
Usually, it's strontium (Sr, #38). It burns a bright red as it oxidizes. This distinctive color is also evident during flame tests of strontium solutions.
Flame tests in daily life?
Fireworks
Uses of flame tests in industry?
There are a few different applications of a flame test. These applications include testing for specific chemicals, checking some items specifically for poisonous chemicals, and testing fireworks.
Why use flame tests in forensic science?
Flame tests allow you to get some idea of what substances make up a given sample. It is particularly useful for the identification of polymers, because many of them give off unique burn patterns.
How are flame tests used in forensic science?
Flame tests are used to help identify substances used in murders

What are the techniques used to analyze inorganic chemicals?
Precipitation tests Flame tests Tests on gases Other ions
What is the flame color of Lead II Nitrate?
Lead compounds tend to be blue in flame tests
Why can you not use flame tests to identify all the elements?
1. not all elements give colour to the flame 2. flame test is not always accurate
How do impurities affect the outcome of the flame tests?

What is the method identifying metal?
there are many tests but flame test, colour and spectroscopy..are the prilimnary tests for identifying metals.
Which mineral tests are the most helpful?
Streak is one of the most useful tests
