Kimia Unsur • Part 3: Logam Alkali (Kelimpahan, Sifat, Reaksi, Pembuatan, Kegunaan)

This video provides an introduction to alkali metals in Group 1A, including Hydrogen, Lithium, Sodium, Potassium, Rubidium, and Francium. It covers their abundance in nature, molecular formulas like Eli (aluminosilicate) and Amblygonite (AliPO4), and electron configurations using Bohr's atomic model and quantum mechanics. The physical properties discussed include density, melting point, flame color, and reactivity characteristic of alkali metals. Furthermore, the video explains the chemical properties such as reactions with water, hydrogen gas, hydrides, oxygen, halides, and electrolysis, along with various practical applications like Lithium in smartphones, Sodium in street lighting, and Chloride as a cooking seasoning.
