A difficulty that may be found in using the flame test is eye imperfection. Another is subjectivity when it comes to perceiving the colors.

What do flame test show about the structure of atoms?
The flame test is only for qualitative identification of some chemical elements.
Is flame coloration a test for the metallic ion or for the nitrate ion?
flame coloration is a test for the Metallic ion because the metallic ions will enter an exited state and release photons energy, in the form of light, as they return to their ground state.
What element often causes difficulties interpreting a flame test?
Sodium(Na)?
Which element couse difficulties in flame tests of other elements?
sodium
How is a Bunsen burner used to identify a substance?
The role of Bunsen burner is to heat; some metallic ions have specific colors in the flame.
What gas is used when a candle gives out red flam?
The colour of a candle flame does not depend on the material being burned. Colours depend on the presence of various metallic atoms in the flame. For various shades of red the material could be:CalciumLithiumMercuryRadiumYttriumZirconium
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.
What is the colour of fermium?
We are not sure because fermium is a lab made element and a pure metal sample has not yet been prepared. However it is a member of the actinide series.The alloy of fermium and ytterbium is shiny and silver.
What are facts antimony?
Antimony is an element that is metallic and can be found in four allotropic forms. It is used to make flame proof things like paint and battery plates.
What color flames do you get when you burn aluminum?
when aluminium sulphur is burnt in a blue flame the flame will turn to an orange flame
When is flame emission spectroscopy used?
It can be used for element identification and can used in Atomic spectroscopy and can be used to help "atoms with low ionization potentials become ionized."
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.
