• A. The order of hydration enthalpies of alkaline earth cations $B{e}^{2+}<M{g}^{2+}<C{a}^{2+}<S{r}^{2+}<B{a}^{2+}$
• B. Lithium and Magnesium show some similarities in their physical properties as they are diagonally placed in periodic table
• C. Lithium is softer among all alkali metals
• D. Lithium chloride is deliquescent and crystallises as a hydrate, $LiCl\cdot H_{2}O$
