1. Module 1 Periodicity: Period 3 Atomic Radius
Nuclear charge increases
Outer electrons attracted more
NO additional shielding

2. Module 1 Periodicity: Period 3 First Ionisation
Complicated!
General increase as nuclear charge increases

3. Module 1 Periodicity: Period 3 Electronegativity
Number of protons increases
Attraction of electrons increases

4. Module 1 Periodicity: Period 3 Melting Point
Na,Mg,Al Metallic
Si Macromolecular
P,S,Cl Simple mol
Ar Atomic

5. Module 1 Periodicity: Period 3 Boiling Point
Na,Mg,Al Metallic
Si Macromolecular
P,S,Cl Simple mol
Ar Atomic

6. Module 1 Periodicity: Group II Atomic Radius
Increase in number of shells
Outer most electrons further From nucleus

7. Module 1 Periodicity: Group II First Ionisation
Atomic radius increases
Outer most electrons become shielded

8. Module 1 Periodicity: Group II Electronegativity
Size of ion increases
Size to charge ratio decreases
Covalent character of compounds decreases

9. Module 1 Periodicity: Group II Melting Point
All metallic
Charge to size ratio decreases
Less attraction to delocalised electrons
Be,Mg hexagonal close packed
Ca,Sr face centred cubic
Ba body centred cubic
