Bbc: Gcse Bitesize: Properties of Materials

This site provides a list of the topics and links to the Physics (Combined Science)courses offered in GCSE Bitesize and a list of contents of each. The topics include the following: Energy, Electricity, Matter, Radioactivity, Forces,...

Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level. Group 1 elements are reactive metals called the alkali...

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between...

Copper can be extracted from its ore by heating it with carbon. Impure copper is purified by electrolysis in which the anode is impure copper, the cathode is pure copper and the electrolyte is copper sulfate solution. It provides links...

An explanation of atomic structure and the element groups in the periodic table using plain language. Supported by diagrams and charts.

Light travels as waves. Waves can be described by their amplitude, wavelength and frequency. The speed of a wave can be calculated from its frequency and wavelength.

The elements in Group 7 of the Periodic Table are called the halogens. They include chlorine, bromine and iodine. Learn about their properties and uses, then take a quiz.

This lesson focuses on the physical properties of halogens, Group 7 elements on the Periodic Table. It includes the physical properties of the elements, provides a graph showing the melting and boiling points of the halogens, and links...

The alkanes, alkenes, alcohols and carboxylic acids are four different homologous series of organic compounds. Their different chemical properties are due to their characteristic functional groups. This lesson focuses on Alkanes...

This lesson focuses on Fractions including the properties of fractions, and complete and incomplete combustion. Links to a video and a test are provided.
