Beryllium exhibits anomalous properties that strongly differentiate it from the rest of Group 2. Whi — s Block Elements Chemistry Question

💡 Solution & Explanation

Demonstrating its diagonal relationship with Aluminium, Beryllium is rendered completely passive by cold, concentrated $HNO_3$. The acid acts as a strong oxidizing agent, rapidly forming a tough, inert protective film of $BeO$ on the metal's surface, halting further reaction.
