Alkali Metals
What do lithium batteries, table salt and firework rockets have in common?
Plastic
Plastic has been around for not longer than roughly 100 years, and the synthetic material is a brilliant invention. Its production is cheap, it can take almost any possible form, it is light-weight, versatile and, above all, inexpensive.
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.
