Periodic Table Part 2: Alkali Metals (Li, Na, K, Rb, Cs, Fr)

The video tutorial covers the alkali metals, detailing their group numbering, properties, natural sources, preparation, reactivity, and applications. It explains the two methods of numbering groups in the periodic table, focusing on the newer method. The tutorial highlights the common properties of alkali metals, such as their electron configurations and ionization energies. It discusses the natural sources of these metals and their rarity, especially francium. The video also covers the preparation methods and reactivity of alkali metals, including their reactions with water and alcohols. Finally, it explores various applications, such as lithium in batteries and sodium in lamps.

Describe the reactivity of alkali metals with water.

What are some applications of lithium as mentioned in the text?

Why is francium considered to have no practical applications?
