CH40163: Advanced f-block chemistry
|Supplementary Assessment:||Like-for-like reassessment (where allowed by programme regulations)|
|Requisites:||Before taking this unit you must (take CH10133 and take CH20147) or (take CH10134 and take CH20148)|
To provide an understanding of the chemistry of the 4f (lanthanide) and 5f (actinide) elements and their increasingly technologically important compounds. To contrast the chemistry of the lanthanides and actinide elements with each other and with the chemistry of the d-block elements.
At the end of the unit the students will:
* understand the influence of the 4f (lanthanide contraction) and 5f valence orbitals upon the chemistry of the lanthanide elements.
* know and understand the basic solid state, coordination chemistry and organometallic chemistry of the 4f and 5f elements.
* be able to evaluate and predict the differences in the chemistry of lanthanide complexes and actinide complexes in terms of the oxidation states, ionisation energies and redox chemistry.
* be able to compare and contrast the chemistry of the f-block element with those of the d-block, identifying differences in the chemistries of the two sets of elements in terms of their oxidation states, redox properties and coordination numbers.
