Question

"$N{a}_{2}C{O}_3$ is more thermally stable than $L{i}_{2}C{O}_3$."
Answer whether the above statement is true or false.
If true enter 1, else enter 0.

Answer 1

As we move down the alkali metal group, the electropositive character increases and as a result, the thermal stability of alkali metal carbonates increases down the group.

Lithium Carbonate is not thermally stable and has the lowest thermal stability among its group members owing to its anomalous small size and high charge density. It decomposes without heating to form carbon dioxide and lithium oxide. On the other hand. Na is larger in size than Li and its compound, $N{a}_{2}C{O}_3$ is a stable compound.

Hence, the correct answer is 1.
