Which of the carb

Answer :

Beryllium carbonate is unstable and is kept in CO2 atmosphere to avoid decomposition. Beryllium is also the least electropositive element out of the group due to the atomic size. BeCO3 decomposes to form BeO and CO2 as carbonates of all alkaline earth metals decompose to give metal oxide and carbon dioxide. This reaction is reversible, hence to shift the equilibrium to the right, BeCO3 is placed in CO2 atmosphere.
