recall that the nuclei of some atoms are unstable, and that these
atoms are radioactive; recall the different properties of alpha,
beta and gamma radiations; use nuclear symbols to write
equations for nuclear processes, both fusion and
radioactive decay;
understand the way that ideas behind the Periodic Table
developed historically;
recall that the Periodic Table lists elements in order of
atomic (proton) number and groups
elements together according to their common properties;
interpret periodic trends in the properties of elements, in terms
of: melting point and boiling point, electrical conductivity,
ionisation enthalpy; relate ease of ion formation to ionisation
enthalpy; write equations for the first and successive ionisation
enthalpies of an element; use given data to describe trends in a
group of the Periodic Table and to make predictions
concerning the properties of an element in the group;
write and interpret balanced chemical equations; describe and
compare the following properties of the elements Mg, Ca, Sr, Ba
in Group 2: reactions of the elements with water, acid-base
character of the oxides and hydroxides, thermal stability of the
carbonates, solubilities of hydroxides and carbonates;
outline the formation of elements in stars by nuclear fusion
processes; explain the occurrence of absorption and emission
atomic spectra; interpret the atomic emission spectrum of
hydrogen in terms of changes in electronic energy levels;
