Question

Why do you think the chemicals have to be heated in the flame first before the colored light is emitted?

Answer 1

Answer:

The chemicals have to be heated in the flame first before the colored light is emitted because the electrons get excited when they were heated by an electric field and that is when they jump to a higher energy shell and emit light.

Answer 2

The chemicals have to be heated in the flame first before the colored light is emitted because :-

• When a chemical is allowed to heat up the electrons present in the atom get excited. The excited electrons move to the higher excited state that is the higher energy level.
• When these same electrons return again to their original state light energy is emitted. This is why heating is required in order to emit light.
• The light colour is always different for different elements and different energy levels.
