Alkalimetalle are highly reactive metals from the first main group of the periodic table, characterized by their unique properties and significant industrial applications.
Key points:
- The group includes Lithium, Sodium, Rubidium, Cesium, and Francium (radioactive)
- Alkalimetalle Eigenschaften include soft texture, high reactivity, and silver-like appearance
- They demonstrate distinctive Alkalimetalle Flammenfärbung (flame coloration)
- Alkalimetalle Reaktion mit Wasser produces metal hydroxides and hydrogen
- Alkalimetalle Vorkommen is exclusively in compound form due to high reactivity
