Halogens
The compounds of halogens are - with the exception of astatine - widespread, can be encountered in nature and are versatile substances. This fact is taken up on this DVD in order to teach the students the chemistry of the halogens by illustrating their special qualities and explaining the correlation of their structure with their chemical properties. In the first part, an overview of the element group of halogens lays emphasis on the common as well as on the distinguishing characteristics of fluorine, chlorine, bromine and iodine. In a second part, the specific properties of fluorine and chlorine are presented. This topic is linked to the students‘ everyday experience (fluorine as a protection against caries, chlorine as a disinfectant, etc.) on the one hand. On the other hand, the DVD presents carefully selected experiments. As a rule, they are of a kind that can only be realized with difficulty, or high expenditure in the chemistry classroom. With the help of these experiments, students are introduced to the chemistry of the halogens in a way that enables them to draw conclusions on the basis of their observations.
Noble Gases
Xenon, Helium, Neon, Argon, Krypton and the radioactive Radon belong to the noble gases. These form the family of noble gases as the elements of the eighth group of the periodic table. All of them are colourless and odourless, non-inflammable and non-toxic. Their most striking chemical property is their inertness. This can be explained by their electron arrangement, termed noble gas configuration and represents a particularly stable and therefore low-energy state. The noble gases are to be found in scant amounts in our air from which they are also distilled. Helium is mainly extracted from natural gas. In everyday life, we encounter noble gases for example as shielding, filling or buoyant gases and in fluorescent tubes. The shell model describes the structure of the atoms. It is based on the distribution of electrons in restricted areas at a fixed distance around the core of the atom.
