Lithium and Magnesium exhibit numerous similarities. Which of the following chemical behaviors are c — s Block Elements Chemistry Question

💡 Solution & Explanation

Both form nitrides ($Li_3N$, $Mg_3N_2$) and their carbonates ($Li_2CO_3$, $MgCO_3$) decompose on heating. Their chlorides are highly deliquescent and form hydrates ($LiCl \cdot 2H_2O$ and $MgCl_2 \cdot 8H_2O$ or $6H_2O$). Statement C is incorrect because both form only monoxides ($Li_2O$, $MgO$) when burnt in air; neither forms superoxides.
