Factors that effect the ionisation energy.

HideShow resource information
The size of that attraction will be governed by...
The charge on the nucleus, The distance of the electron from the nucleus, The number of electrons between the outer electrons and the nucleus, Whether the electron is on its own in an orbital or paired with another electron.
1 of 10
Which has a higher ionisation energy, Lithium or Helium? Why?
Helium - less sheilding so the electron has a greater attraction from the nucleus.
2 of 10
Write out the electronic structure of phosphorus? (15)
1s2 , 2s2 , 2p6 , 3s2 , 3p3
3 of 10
Write out the electronic structure of phosphorus using an inert gas symbol shorthand.
[Ne] 3s2, 3p3
4 of 10
Write out the equation for the first ionisation energy of Magnesium:
Mg(g) ------> Mg+(g) +e-
5 of 10
What is the deifinition of an ionisation energy?
The energy required to remove one mole of electron from one mole of gaseous ions.
6 of 10
What are the exceptions to the electron arrangement system? Why?
Cu - takes one electron from 4s and creates a full 3d sub-shell. Cr - takes one electron from 4s and now 3d has one electron in each orbital.
7 of 10
Write out the subshells in their energy order:
1s,2s,2p,3s,3p,4s,3d,4p,5s,4d
8 of 10
Why are electrons shown as arrows in opposite directions?
Because they interact with each other, this is also why it is easier to remove a paired electron as the two electrons repell each other.
9 of 10
Do higher energy levels (sub-shells) have more or less energy? and does this make it harder or easier to remove them?
Higher sub-shells have more energy and this makes it easier to remove them.
