Why superoxides of of alkali metals are paramagnetic ?

Text Solution

AI Generated Solution

To understand why superoxides of alkali metals are paramagnetic, we can break down the explanation into several steps: ### Step 1: Define Superoxides Superoxides are a type of oxide where the oxygen has a higher oxidation state than in typical oxides. For alkali metals, the superoxide can be represented as \( MO_2 \), where \( M \) is the alkali metal. **Hint:** Remember that superoxides contain more oxygen than typical oxides, which affects their electronic structure. ### Step 2: Identify the Ion Formation ...
