Ionisation Energy

We need to know a fair bit about Ionisation Energy:

  1. Define 1st I.E.
  2. Justify the trend in 1st I.E. down a Group
  3. Justify the trend in 1st I.E. across a Period
  4. Use consecutive I.E. values to infer electron configuration/number of valence electrons.


  1. The sound quality is pretty darn terrible to begin with. We should be more careful that we don't cover the microphone.

  2. I agree. I suggest looking at the Khan Academy one instead.
