alkalimetallid

Alkalimetallid, also known as alkali metals, are a group of chemical elements in the periodic table, specifically those in group 1. This group includes lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Alkalimetallid are highly reactive metals, with properties such as low density, low melting points, and high electrical conductivity. They are soft and can be easily cut with a knife. Alkalimetallid readily lose their outermost electron to form a positive ion, which is why they are called alkali metals, as they form alkaline hydroxides when reacted with water. Due to their high reactivity, alkalimetallid are typically stored under oil to prevent reaction with air or water. They have various applications, including in batteries, as reducing agents in chemical reactions, and in the production of certain alloys. However, their reactivity also poses challenges, such as the need for careful handling and storage to prevent hazardous reactions.
