Identify the amphoteric compounds from the following list of s-block oxides and hydroxides. — s Block Elements Chemistry Question

💡 Solution & Explanation

Beryllium exhibits anomalous behavior compared to the rest of Group 2. Because of its exceptionally small size and high ionization enthalpy, both its oxide ($BeO$) and hydroxide ($Be(OH)_2$) are amphoteric, reacting with both acids and strong bases (forming beryllates). The oxides and hydroxides of other s-block elements are basic.
