Precipitation

This resource, from the Royal Society of Chemistry, is designed to support students understanding and explanations of chemical reactions at the particle level.

Students are provided with diagrams representing the particles present in the reaction between silver nitrate solution and sodium chloride solution...

Types of Chemical Reaction

This resource, from the Royal Society of Chemistry, provides students with a range of chemical reactions which they have to identify.

The types of chemical reaction which are included are: displacement, neutralisation, oxidation, reduction and thermal decomposition reactions. It is primarily designed for...

An Analogy for the Atom

This resource, from the Royal Society of Chemistry, is designed for students who have already studied the topic of atomic structure, intra-atomic forces and ‘the atom is a tiny solar system’ comparison. Students are provided with diagrams showing a simple model of an atom and of the solar system and asked questions...

Chemical Stability

This resource, from the Royal Society of Chemistry, asks students to compare the stability of various triads of related species.

There are seven questions in the set, the first four compare an atom with two of its ions (sodium, chlorine, carbon and beryllium) and are suitable for able students aged 14-16 as...

Stability and Reactivity

This resource, from the Royal Society of Chemistry, is an assessment task designed to elicit students’ ideas about chemical stability and reactivity.

The activity is intended to act as a starting point for discussing these ideas in the classroom. Students are provided with diagrams representing the electron...
