what property are alkaline earth metals?
428330
Alkaline earth metals: A group of chemical elements in the periodic table with similar properties: shiny, silvery-white, somewhat reactive at standard temperature and pressure. They readily lose their two outermost electrons to form cations with charge +2.
865933
In chemical terms, all of the alkaline earth metals react with the halogens to form the alkaline earth metal halides, all of which are ionic crystalline compounds (except for beryllium chloride, which is covalent).
87328
In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides. All the alkaline earth metals except beryllium also react with water to form strongly alkaline hydroxides which should be handled with great care. ... All compounds that include beryllium have a covalent bond.

Alkaline Earth metals are very reactive because they readily give up their two valence electrons to achieve a full outer energy level, which is the most stable arrangement of electrons.

The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.

Alkaline Earth Metals. The alkaline earth metals are the second most reactive family of elements. Beryllium, magnesium, calcium, strontium, barium and radium are all shiny, and silvery-white. They all have low densities, melting points and boiling points, and they tend to form solutions with a pH greater than 7.

The second column on the periodic table of the chemical elements is collectively called the alkaline earth metal group: beryllium, magnesium, calcium, strontium, barium, and radium. Because the outer electron structure in all of these elements is similar, they all have somewhat similar chemical and physical properties.

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Pure samples of most of the alkaline earth metals can be obtained by electrolysis of the chlorides or oxides. ... The most important alkaline earth organometallic compounds are Grignard reagents (RMgX), which are used to synthesize organic compounds.

The alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure. All the alkaline earth metals readily lose their two outermost electrons to form cations with a 2+ charge.

The alkaline earth metals are a group of elements in the periodic table. They are all in the second column of the periodic table. They are sometimes referred to as the group 2 elements.
653732
Alkaline Earth Elements Have Two Electrons in Their Outer Energy Level.

The alkaline earth metals are named after their oxides, the alkaline earths, whose old-fashioned names were beryllia, magnesia, lime, strontia, and baryta. These oxides are basic (alkaline) when combined with water.

The alkaline-earth elements are highly metallic and are good conductors of electricity. They have a gray-white lustre when freshly cut but tarnish readily in air, particularly the heavier members of the group. Beryllium is sufficiently hard to scratch glass, but barium is only slightly harder than lead.

Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
