Alkaline-earth metals are Group 2 elements that easily lose electrons to form positive ions. They have basic oxides and are highly reactive reducing agents. Learn about their occurrence, history, and applications.
The meaning of ALKALINE EARTH METAL is any of the divalent strongly basic metals of group II of the periodic table comprising beryllium, magnesium, calcium, strontium, barium, and radium —called also alkaline earth.
Learn about the properties, uses, and examples of alkaline earth metals, the Group 2 elements with two s electrons in their outer shell. Find out how they differ from alkali metals and why they are important for bone, oyster shells, and fireworks.
Alkaline earth metals are a group of highly reactive elements with two valence electrons in the s-block of the periodic table. They react with water, oxygen, and halogens, and have various applications in industry, medicine, and biology.
Learn about the physical and chemical behaviour of alkaline-earth metals, a group of highly metallic and reducing elements with similar electronic configurations. Find out their melting and boiling points, crystal forms, solubility in ammonia, and applications in various fields.
Alkaline earth metals are six chemical elements in group 2 of the periodic table, such as calcium, magnesium, and barium. They are shiny, silvery-white, reactive metals that form cations with charge +2 and compounds with halogens, oxygen, and water.
Alkaline earth metals are six elements in the second column of the periodic table with two electrons in the outer shell. They are shiny, silver-colored metals that form cations with a 2+ charge and react with halogens and oxygen.
Alkaline earth metals are elements in Group 2 of the periodic table and include beryllium, magnesium, calcium, strontium, barium, and radium. They are characterized by having two electrons in their outermost energy level which they readily lose to form divalent cations.
alkaline earth metal, Any of the six chemical elements in the second leftmost group of the periodic table (beryllium, magnesium, calcium, strontium, barium, and radium).
The Group 2 metals have a particular name: the alkaline earth metals. The name is derived from the observation that they have such high melting points (Table \(\PageIndex{4}\).1) that they remain solids (earths) in a fire.
