AI Generated Solution

The correct Answer is:
To determine which alkali metal is the most abundant, we can follow these steps: ### Step-by-Step Solution: 1. **Identify Alkali Metals**: The alkali metals in the periodic table include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). 2. **Research Abundance**: Look into the abundance of these alkali metals in the Earth's crust and in nature. Sodium and potassium are known to be the most abundant among them. 3. **Compare Abundances**: - Sodium (Na) is the 7th most abundant element in the Earth's crust. - Potassium (K) is the 8th most abundant element in the Earth's crust. 4. **Conclusion**: Since sodium is more abundant than potassium, we conclude that sodium is the most abundant alkali metal. 5. **Final Answer**: The most abundant alkali metal is sodium (Na).
