3. Atomic Radius vs Atomic Number The distance from the centre of the nucleus to the outermost electron. As the number of energy levels increases so does the atomic radius. As the number of protons in an energy level increases the radius decreases.

4. Ionization Energy vs Atomic Number The amount of energy required to remove the outermost electron. The closer the electron is to the nucleus the more energy required to remove it.

5. Electron Affinity vs Atomic Number The attractive force between atomic nucleus and electrons. The smaller the atomic radius the greater the electron affinity.

6. Electronegativity vs Atomic Number The strength with which an atom pulls on a electron pair. The smaller the atom the bigger the electronegativity.
