Definitions in Chemistry

This resource, from the Royal Society of Chemistry, provides students with an opportunity to discuss and give a critique of basic chemical definitions for the terms element, compound, atom, and molecule.

By engaging in the activity students can explore and reveal their own understanding of these concepts....

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...

Spot the Bonding

This resource, from the Royal Society of Chemistry, provides a relatively quick way of assessing students’ awareness of different bond types. Topics covered in this material are chemical bonding including: ionic, covalent, metallic, polar, hydrogen, dipole-dipole, van der Waals, solvation, dative, double,...

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...

Word Equations

This resource, from the Royal Society of Chemistry, assesses students’ ability to complete word equations through a set of practice exercises. The word equations are for the following examples:

• Reaction between acids and alkalis.
• Reaction between acids and metals.
• Reaction between acids and...

Ionic Bonding

This resource, from the Royal Society of Chemistry, is designed to elicit alternative conceptions about ionic bonding that have been found to be commonplace among students. Students are provided with a diagram showing part of a slice through a three dimensional crystal structure of sodium chloride, along with...

The Melting Temperature of Carbon

This resource, from the Royal Society of Chemistry, is suitable for students who have studied bonding and structure and can calculate relative molecular mass.

Students are provided with information on some elements which they use to calculate the formula mass of other elements. They are then provided with...

Revising the Periodic Table

This resource, from the Royal Society of Chemistry, is intended for students in the 14–16 year old age range, who have studied the Periodic Table.

This exercise is based on concept mapping, an important method for exploring student’s ideas and a useful study technique. The exercise provides a concept map...
