Correct option is A
The correct answer is (a) Both the statements are true.
Explanation:
- The metals high up in the reactivity series are highly reactive and tend to form stable compounds, which makes it difficult to extract them from their ores.
- These metals include elements like potassium, sodium, calcium, and magnesium.
Information Booster:
- To obtain these metals from their compounds, electrolytic reduction is commonly used.
- In this process, electrical energy is used to break down the compound (usually a molten or dissolved metal salt) into its component elements.
- For example: Sodium can be extracted from molten sodium chloride (NaCl) through electrolysis. Aluminum is obtained from aluminum oxide (Al₂O₃) through the process of electrolysis.
