This video is going to be about the flame test to identify the metoion. A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primary metoion, based on each element's characteristic emission spectrum. The flame tests are most useful for some metals than others. It is very useful for group 1 metals. This flame test provides a good way of quickly identifying the metoion present. And these are some color of the metoion. The color originates from the movement of electrons in the metoion. When heated, electron gets energy and they are excited into higher energy level. And this is called the absorption process. As electrons are more energetic, they are unstable, so they tend to fall back to the lower energy level. When they do that, they release energy as light. And this light has a characteristic flame colors of different metoion due to varying electron transitions. This is the emission process. Flame tests is relatively quick and simple. We can do this quite quickly in laboratory. All you need is the Bunsen burner, some cotton stick, and of course the test sample.
