The Periodic Table: chemical periodicity

Period 3: Periodicity of Physical PropertiesSign up

be able to represent data, in a graphical form (including the use of logarithms of first ionisation energies on a graph) for elements 1 to 36 and hence explain the meaning of the term 'periodic property' · be able to explain: (i) the trends in melting and boiling temperatures of the elements of Periods 2 and 3 of the Periodic Table in terms of the structure of the element and the bonding between its atoms or molecules; (ii) the general increase and the specific trends in ionisation energy of the elements across Periods 2 and 3 of the Periodic Table; (iii) the decrease in first ionisation energy down a group
