Scheme of work

Ref	Lesson pack	Structure	Worksheet	Quiz	Lab tab
28.1	Physical properties of transition elements Titanium to copper sit in the middle of period 4, filling the 3d subshell.	Frayer Model	6 Q, 16 marks	8 MCQ	tab 1
28.2	Complex ions and ligands A transition metal ion surrounded by molecules or ions that each donate a lone pair is a complex.	Connect-Extend-Challenge	6 Q, 15 marks	8 MCQ	tab 2
28.2	Ligand exchange Add ammonia, hydroxide or concentrated hydrochloric acid to a solution of a transition metal ion and the ligands around the metal are replaced.	Anticipation / Reaction Guide	6 Q, 15 marks	8 MCQ	tab 3
28.2	Variable oxidation states and redox Because transition metals have several stable oxidation states, their compounds make excellent oxidising and reducing agents.	Round Table	6 Q, 16 marks	8 MCQ	tab 6
28.3	Colour of complexes In an isolated ion the five 3d orbitals have the same energy.	Think-Pair-Share	6 Q, 16 marks	8 MCQ	tab 4
28.4	Stereoisomerism in complexes Two complexes can have the same metal, the same ligands and the same bonds yet be different substances, because the ligands sit in different places in space.	Mix-Pair-Share	6 Q, 15 marks	8 MCQ	tab 5
28.5	Stability constants, Kstab Ligand exchange is an equilibrium, so it has an equilibrium constant.	Round Table	6 Q, 15 marks	8 MCQ	tab 3

Each pack holds the plan, worksheet and quiz for its lesson. Teach the rows in order; the lab tabs match the student lessons.
