Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Potassium and sodium.
Key Points
- Potassium and sodium are highly reactive alkali metals that react so vigorously with oxygen and moisture in the air that they can catch fire if exposed to the open environment.
- Both potassium and sodium react exothermically with oxygen, forming their respective oxides, and can ignite spontaneously due to the heat generated in these reactions
Additional Information
- Transition metals like iron and copper react with oxygen but at a much slower rate, often forming a protective oxide layer.
- Magnesium also reacts with oxygen, especially when heated, producing a bright white flame and forming magnesium oxide.
