F332 - Module 1 (ES) Elements from the Sea

Inorganic chemistry and the Periodic Table

Recall that the Periodic Table lists elements in order of atomic (proton) number and groups elements together according to their common properties

Recall the classification of elements into s-, p- and d-blocks:

Write formulae for compoundsformed between these ions and other given anions and cations;

Recall the meaning of the term ionisation enthalpy, write equations for the successive ionisations of an element, and explain periodic and group trends in the properties of elements in terms of ionisation enthalpy;

Recall the following physical properties of the halogens:

Explain physical state and volatility of the halogens in terms of intermolecular bonds;

Use given information to compare different methods of manufacturing chemicals industrially, in terms of atom economy, percentage yield, batch versus continuous process, siting the plant, cost of process and raw materials, waste disposal, safety

Explain and compare the relative reactivity of the halogens in terms of their oxidising ability

Describe and write half-equations for the redox changes which take place:

Recall the reactions between halide ions (X–) and silver ions (Ag+) and write ionic equations to represent these precipitation reactions;

(q) explain the risks associated with the storage and transport of the halogens (fluorine to iodine);

Recall and describe some uses of halogen compounds which must be weighed against these risks, including:
