Least reactive alkali earth metal
NettetReactivity of Group 1 Elements. Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the … NettetLeast reactive alkaline earth metal: Beryllium Be is the least reactive alkaline earth metal because as we move from top to bottom in a group the reactivity increases. The increase in reactivity is due to the reason that as we move down in a group the size of the atom increase, due to which the force of attraction between the nucleus and valence …
