What are the properties of Group 2 elements and their oxides?

Group 2 elements have similar properties, including low electronegativity and reactivity, and form basic oxides.

Group 2 elements, also known as alkaline earth metals, are located in the second column of the periodic table. They have two valence electrons and low electronegativity, making them highly reactive. As you move down the group, the atomic radius and reactivity increase.

The Group 2 elements react with oxygen to form oxides, which are basic in nature. For example, magnesium oxide (MgO) is a white solid that is commonly used in the production of cement and as a refractory material. Calcium oxide (CaO), also known as quicklime, is used in the production of cement, as a soil stabilizer, and in the production of steel.

The oxides of Group 2 elements also have important biological properties. For example, calcium oxide is used in the production of antacids to neutralize stomach acid. Calcium carbonate (CaCO3), another oxide of Group 2 elements, is a common supplement for maintaining bone health.

In conclusion, Group 2 elements have similar properties, including low electronegativity and reactivity, and form basic oxides. These oxides have important industrial and biological applications.
