Quiz your students on types of bonding

The topics covered in this Starter for ten activity are: covalent dot and cross; ionic dot and cross; which typr of chemical bond; co-ordinate bonding; electronegativity and polarity; intermolecular forces; shapes of molecules; and properties of bonding.

Example questions
