Alkali Metals
Properties, Examples, Relationship
What do lithium batteries, table salt and firework rockets have in common? All of them contain compounds of alkali metals. Alkali metals are members of the first group of the periodic table of the elements. The metals in this group are lithium, sodium, potassium, rubidium, caesium and francium. The word “alkali“ is derived from the Arab “al-qalya“ for potash, the colloquial term for potassium carbonate. In this film we want to take a closer look at the representatives of this family of elements, compare their properties, investigate the chemical behaviour and see where we encounter their chemical compounds in everyday life. Alkali metals and alkaline solutions – also called basic solutions – are noxious for the skin. Therefore, additional protective gloves should be worn – apart from the obligatory protective goggles required in laboratory work.

Matching
Pupils Practise Inclusion
When people come together, no matter under what concomitant circumstances – ultimately, it is about how these people meet and how openly they interact with one another.
Youth Movement
Dancing until your feet hurt: Here, at the meeting on the Hoher Meissner near Kassel, 3,500 participants from Boy Scout associations, youth and Wandervogel groups from all over the German-speaking region have gathered. They want to celebrate, simply get to know each other and commemorate a historic anniversary.
