Question

# Given the statement is “$L{i_2}C{O_3}$ and $N{a_2}C{O_3}$ are thermally stable.” Answer whether the above statement is true or false. If true enter 1, else enter 0.

The thermal stability of group 2 element increases as we move down in the group. All the alkali carbonates are stable to heat except lithium carbonate $L{i_2}C{O_3}$, because lithium carbonate is a covalent compound. On moving down in the group of alkali metal, the electropositive character of the metal increases which increases the thermal stability of the metal carbonate.
Therefore, the above statement $L{i_2}C{O_3}$ and $N{a_2}C{O_3}$ are thermally stable is false.
