What can you work out from successive ionisation energies of an element? | The number of electrons in each shell of the atom and which group the unknown element is in |
What does a graph showing successive ionisation energy look like? |

What happens to successive ionisation energy within each shell? | Within each shell, successive ionisation energies increase |
Why do successive ionisation energies increase within each shell? | Electrons are being removed from an increasingly positive ion - there's less repulsion amongst the remaining electrons, so more energy is needed to remove the next electron |
What do the big jumps in successive ionisation energy indicate? | When a new shell is broken into - an electron is being removed form a shell closer to the nucleus. This can be used to work out which group the element belongs to |
