come to think of it, I swear the questions are always about emission :/. I would include the following points: electrons absorb energy; and become excited (lol); and are promoted to a higher energy level.; the energy level are quantised- so electrons CANNOT be between levels ; the frequency/energy required to make a jump between levels is specific to each gap; (E=hf) ;so energy/frequency absorbed is specific; hence the distinct black lines. Don't forget to include E=hv/ E=hf somewhere in your answer-. there's usually a mark for including it in your explanation. I think these are the main points just modify and add/remove some bits to suit the question |
