Ionic RadiusThe ionic radius is the radius of both ions within a crystal lattice. As you go down the family, the ion radius increases due to extra layers of electrons, and along a period the ion radius the positive ions begin to fall. However, along a period of a negative ion there is little change.

ElectromagnegativityElectronegativity is the tendency for an atom to attract a pair of electrons. The Pauling scale is used to determine this. Fluorine is the most electronegative element. So reaching the conclusion that any element closest to it will be more electronegative, thus the lower the period number and the higher the group, the more likely it is electronegative.
