Question

Lithium, sodium, and potassium are Group I metals. Explain why these metals cannot be extracted from their ores by heating the ores with carbon.

Answer 1

Step-by-step explanation:

Metals in the top of the reactivity level i.e. metals like sodium, magnesium, calcium, etc cannot be obtained from their compound by heating with carbon as they are very reactive. Electrolytic reduction is used to obtain such metals.
