Why is beryllium amphoteric in nature?
(N/A) Beryllium exhibits amphoteric character because its oxide $(BeO)$ and hydroxide $(Be(OH)_2)$ can react with both acids and bases to form salts and water.
For example,it reacts with $HCl$ (acid) to form $BeCl_2$ and with $NaOH$ (base) to form sodium beryllate $(Na_2[Be(OH)_4])$.
