Learning Outcomes
Students should be able to:
Ionic Bonding
(a) describe the formation of ions by electron loss / gain in order to obtain the electronic configuration of a noble gas
(b) describe the formation of ionic bonds between metals and non-metals, e.g. NaCl; MgCl2
(c) relate the physical properties (including electrical property) of ionic compounds to their lattice structure
Covalent bonding
(a) describe the formation of a covalent bond by the sharing of a pair of electrons in order to gain the electronic configuration of a noble gas
(b) describe, using ‘dot and cross’ diagrams, the formation of covalent bonds between non-metallic elements, e.g. H2, O2, H2O, CH4 and CO2
(c) deduce the arrangement of electrons in other covalent molecules
(d) relate the physical properties (including electrical property) of covalent substances to their structure
