Question

What is Group 2 called?

Answer 1

Group 2 elements are basic in nature, they are most commonly found on the earth's crust or surface. As a result, the phrase "alkaline earth metals" was formed. The following are the properties of Group 2:

1. Beryllium ($\mathrm{Be}$), Magnesium ($\mathrm{Mg}$), Calcium ($\mathrm{Ca}$), Strontium ($\mathrm{Sr}$), Barium ($\mathrm{Ba}$), and Radium ($\mathrm{Ra}$) are all members of Group 2.
2. These elements are likewise not found naturally because they are made from naturally occurring alkaline minerals like slake, limestone, and others that are extremely reactive.
3. They're termed alkaline earth metals because when they react with water, they produce alkaline solutions (hydroxides). Simply said, alkaline refers to a solution that has a pH greater than seven and is basic. As a result, alkaline earth metals are good reducing agents and generate highly basic solutions.
4. Beryllia, Magnesia, Lime, Strontia, and Baryta are the traditional names for the alkaline earth metals, which are named after their oxides, the alkaline earth. When mixed with water, these oxides become basic (alkaline). Early chemists coined the name "earth" to describe nonmetallic compounds that are insoluble in water and resistant to heating, qualities that these oxides share.
5. This group's elements are all denser than water. Pure metals are silvery grey in colour, but when exposed to air, they decolourize quickly due to the formation of an oxide coating on the surface. These metals, like alkali metals, are good heat and electrical conductors. Commercially, all alkaline earth metals are valuable.
6. The general electrical configuration of alkaline earth metals is ${\mathrm{ns}}^2$ has two valence electrons in their outermost shell with the $+2$ ionic charge in compounds.
7. Beryllium is derived from the Greek word Beryllos, which refers to the gemstone beryl. The element is a silver-white metal with a high melting point and is the first of the alkaline earth metals. It is rare in nature and is found mostly in the mineral beryl, which contains aluminium and silicon.
8. Magnesium is the eighth-most prevalent element in the earth's crust and belongs to Group 2. Magnesium is a light, silvery-white metal that is strong. When exposed to air, it creates a thin layer around itself, similar to aluminium, to assist prevent corrosion. When fine magnesium particles are exposed to air, they can catch fire.
9. The periodic table's 20th element is calcium. It's a group 2 metal with no inhabited d-orbital electrons, also known as an alkaline-earth metal. In both the Earth's crust and saltwater, Calcium is the fifth most abundant element by mass (3.4 per cent). Calcium is required for the survival of all living species (including the dead).
10. Because of its strong reactivity with oxygen and water, Strontium is a group 2 element that does not exist as a free element. Only in combinations with other elements, such as Strontianite, does it occur naturally. It is softer than calcium and has a faster rate of water decomposition. It has a silvery appearance at first, but when oxide forms, it turns yellow.
11. The melting point of Barium is 1000K, making it a delicate, silvery-white metal. Barium cannot be found in its pure form in nature due to its reactivity with air, but it can be extracted from the mineral Barite.
12. Radium is radioactive in all isotopes, and several of them glow when exposed to oxygen and water.
