Michaelmas Term (2 lectures) Third Year
A brief comparative survey of the chemistry of the elements:
Cu, Ag & Au (oxidation state +1 only); Zn, Cd & Hg;
Ga, In & T1; Sn & Pb; Sb & Bi.
1. Atomic and elemental properties, and their implications
regarding the stabilities of simple compounds. Occurrence
of the elements (including Biology). Comparison with pre-transition
elements (A metals). Enhanced covalency in compounds of the
post-transition elements. The 'alternation effect'. The semiconductor
->; metal transition in groups 14 etc.
2. The group oxidation states (N). Trends in the stability
of compounds and their structures. Acceptor (Lewis acid) properties.
The ions MN+ in solution; complex formation. The
HSAB principle.
3. The N - 2 oxidation states (the 'inert pair effect').
Trends in stability. Structural consequences of 'lone-pair'
electrons (cf. VSEPR theory). Donor/acceptor properties. The
ions M(N-2)+ in solution.
4. Other oxidation states, including 'mixed-valency'
compounds. Species involving metal-metal bonding (cluster
compounds). Compounds with other metallic elements.
