The elements that make up Group 2 of the periodic table are commonly called the alkaline earth metals. They include beryllium, magnesium, calcium, strontium, barium, and radium. All of these elements contain two electrons in the outermost energy level of their atoms, and they tend to have similar chemical and physical properties.

Alkaline Earth Metals Reactions, Uses, Properties

Halogen and alkaline earth metals. Alkaline earth metals react with halogens and form halides. This reaction is a exothermic reaction. Ca + Cl 2 → CaCl 2. Ba + I 2 → BaI 2. Ammonia and alkaline earth metals. 3Mg + 2NH 3 → Mg 3 N 2 + H 2. Due to release of hydrogen gas, ammonia behaves as an acid. Sulfur and alkaline earth metals reactions
