Periodicity Graphs

The atomic size decreases as you go across the periods. This is due to the increase in the number of protons; as the number of protons increases, the pull on the energy levels increase, so the atomic size decreases.
The first ionisation of the elements increases as you go along a period, as there are more protons acting on the energy level. It then decreases as you move onto the next period, due to the extra energy level.
The melting and boiling points increase along the period in the transition metals (due to their metallic structure) and then decrease in the gases.
