  • Today were going to learn about quantum. Quantum is when electrons orbit around the nucleus on an energy levels.
  • Yes, depending on where they are in the energy level.
  • energy levels are the rings around the nucleus.
  • Now were going to go through the names of the process but one important thing you need to know is energy is in the form of light. Now can anyone guess what absorption means
  • Does the energy change?
  • and absorb means to take in absorb it.
  • OH I don't know
  • Yes, so when an electro takes energy in its called absorption. sometimes the electron will take more energy then it can handle and move up an energy level and thats called excited state.
  • Well what word comes to mind when you hear absorption?
  • Absorb
  • could it be the opposite of absorption?
  • Can anyone guess what emission is
  • so it gives off energy
  • causing it to move down a level?
  • YES! Now youre getting it. So when it gives off so much energy it starts to get weak and gets to its lowest of energy its called ground state.
  • now lets review on this atomic model.
  • then here when it absorbs it it gets too much energy then the level can handle and moves up a level and soon becomes excited stage
  • so that whole process happens over and over it goes to excited state then ground state and its called light emission.
  • so when it emits energy it it moves down a level and soon becomes ground state
