3.1.1 Periodicity

Learners should be able to demonstrate and apply their knowledge and understanding of:

(a, b) The Structure of the Periodic Table

(c) First Ionisation Energy

(d) Metallic Lattices

(e) Giant Covalent Lattices

(f) explanation of physical properties of giant metallic and giant covalent lattices, including melting and boiling points, solubility and electrical conductivity in terms of structure and bonding

{Explanations should be in terms of the types of particle present in a lattice, the relative strength of forces and bonds, and the mobility of the particles involved, as appropriate.}

SEE (d) and (e)

(g) Melting Points across Periods 2 and 3
