Bonding and structure topic check

Practise G2 Chemistry ionic and covalent bonding, particle diagrams and material properties, then check your structure–property explanations.

Learning goals

Describe how atoms lose or gain electrons to form ions, which usually have a noble-gas electronic configuration
Describe ionic bonding between metals and non-metals, such as in NaCl and MgCl₂, using dot-and-cross diagrams
Relate the physical properties of ionic compounds, including electrical conductivity, to their lattice structure
Describe a covalent bond as a shared pair of electrons, with the bonded atoms usually reaching a noble-gas electronic configuration
Draw dot-and-cross diagrams for covalent bonds between non-metals, such as in H₂, O₂, H₂O, CH₄ and CO₂
Deduce the electron arrangement in other covalent molecules
Relate the physical properties of covalent substances, including electrical conductivity, to their structure and bonding
Describe how elements, compounds and mixtures differ
Describe the typical physical properties of solid metals: high melting and boiling points, malleability and good conduction of heat and electricity
Describe an alloy as a mixture of a metal with another element, such as brass or stainless steel
Recognise metals and alloys in structure diagrams
