    Is there a way to predict what colour a metal ion will display in a flame test?

    For example - if I wanted to predict what colour Metal X would display, could I use energy gap informaton and equations to get the wavelength of light emitted and thus the colour?

    Can anyone do the maths and show why, for example, Lithium burns with a red flame?

    Its to do with the oxidation state of the metal, look at where the element is located in the periodic table, and the electron configuration will give you clues. Basically if you go to d - block chemistry, it often gives you a wheel of colour for compounds.
