Question

Electrons take up energy and move to higher energy levels and thus appear coloured how

Answer 1

Answer:

hey mate here is your answer

When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital. Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.

Answer 2

Answer:electrons by taking up energy go to higher energy levels and when they return from their excited state to normal or ground state they radiate energy in the form of radiations which can be of different frequencies depending on the energy which was given to them and hence different colours can be seen .
