Verified by Experts

The correct answer is:

Thermal stability of carbonates increases in a group as we move from top to bottom and decreases in a period as we move from left to right. So, the correct order of thermal stability of given carbonates is :

BeCO 3 < MgCO 3 < CaCO 3 < K 2 CO 3

Be, Mg and Ca present in second group and K present is first group.
