Both alkali metals and alkaline earth metals are s - block elements. They resemble each other respect but still there are certain dismilariaties in their properties due to number of eletrons in the valence shell different atomic radii, ionisation enthalpy, electronegativity etc. Which is least thermally stable ?

1.	Both alkali metals and alkaline earth metals are s - block elements. They resemble each other respect but still there are certain dismilariaties in their properties due to number of eletrons in the valence shell different atomic radii, ionisation enthalpy, electronegativity etc. Which is least thermally stable ?
Answer» `LiCO_(3)` `MgCO_(3)` `BaCO_(3)` `BeCO_(3)` Solution :THERMAL STABILITY increases from `BeCO_(3)` to `BaCO_(3)`
