GCSE Chemistry - Group 1 Alkali Metals #11

The video discusses alkali metals, highlighting their unique properties such as low density and high reactivity compared to other metals. It explains the trends in reactivity and melting points as you move down the group, emphasizing the ease of losing the outer electron. The formation of ionic compounds with non-metals is covered, along with specific reactions of alkali metals with water, chlorine, and oxygen. The video also provides examples of compounds formed and suggests using flashcards for memorization.

How do ionic compounds form between alkali metals and non-metals?

Describe the reaction of alkali metals with chlorine gas.

What types of oxides do alkali metals form when they react with oxygen?
