Vertical column containing elements with similar properties due to the same number of electrons in the outer shell
2 of 9
Periodcity
Trend in properties repeated across each period
3 of 9
First Ionisation Energy
The energy required to remove one electron from each atom in one mole of the gaseous element to form one mole of gaseous 1+ ions
4 of 9
Electron Shielding
The repelling effect of inner shells of electrons repelling outer shell electrons. The more inner shells the large the shielding effect and the smaller the nuclear attraction experienced by the outer electrons.
5 of 9
Successive ionisation energies
Measure of the amount of energy required to remove each electron in turn. An element has as many ionisation energies as it has electrons
