|
Red flame |
Lithium chloride |
|
|
What causes the flame colour |
Cation. Because it is what is changing if it where the anion (chloride) then the colour would stay the same |
|
|
Why is light created |
As they gain energy from the bunsen flame they move to a higher orbit then as they drop back down they release their energy as light |
|
|
Why there's Different colours |
Differences in the amount of energy between electron shells which produce different energy levels of light |
|
|
Any limitations |
Not all metal ions produce a color when heated in a flame e.g. iron and aluminum |
|
|
Not all metals produce light why |
They energy their electrons amit is above or below the visible part of the electromagnetic spectrum |
|
