The alkaline earth metals provide a good example of group trends in properties in the periodic table, with well-characterized homologous behavior down the group. With the exception of Be and Mg, the metals have a distinguishable flame color, brick-red for Ca, magenta-red for Sr, green for Ba and crimson red for Ra.
Alkaline earth metal
The alkaline earth metals are silvery colored, soft, low-density metals, which react readily with halogens to form ionic salts, and with water, though not as rapidly as the alkali metals, to form strongly alkaline hydroxides.For example, where sodium and potassium react with water at room temperature, magnesium reacts only with steam and calcium with hot water:

The Alkaline Earth Metals (Group 2)
Preparation of the Alkaline Earth Metals. The alkaline earth metals are produced for industrial use by electrolytic reduction of their molten chlorides, as indicated in this equation for calcium: Equation 21.22. CaCl2(l) → Ca (l) + Cl2(g) The group 2 metal chlorides are obtained from a variety of sources.
Alkaline Earth Metals
All of the alkaline earths are shiny, silver-colored metals at ordinary temperatures and pressure. These metals are malleable and ductile. The alkaline earth metals tend to be soft, with relatively low densities, melting points, and boiling points for metals. The melting points and boiling points are still much higher than for nonmetals.
12.3: Group II
Table 12.3.1 12.3. 1: Properties of the Group IIA Alkaline-Earth Metals. First and second ionization energies for the alkaline earths (corresponding to removal of the first and second valence electrons) are relatively small, but the disruption of an octet by removal of a third electron is far more difficult.
5 Alkaline Earth Metal Examples: Facts You Should Know
August 12, 2022 by Aditi Roy. Alkaline earth metals are one of the most reactive and shiny six chemical elements of group 2 in the periodic table. Let us discuss in brief about the examples. The examples of alkaline earth metals are listed below-. Magnesium. Beryllium. Strontium. Barium. Calcium.
3.1: The Alkali Metal Elements
The Group 1 metals have a particular name: the alkali metals. This is due to the formation of alkali (basic) solutions upon their reaction with water. Table 3.1.3 3.1. 3 .1 lists the derivation of the names of the alkali metals. Element. Symbol. Name. Lithium. Li. Greek lithos meaning stone.
Alkaline Earth Metals: Definition, Properties, Use, and Types
1. Beryllium. Beryllium (Be) is the first member of the alkaline earth metals and it is also the lightest. It has an atomic number of 4 and an electron configuration of [He] 2s². This element is not very abundant and primarily occurs in beryl, a mineral, together with aluminum and silicon.

Beryllium is used mainly in military applications, but non-military uses exist. In electronics, beryllium is used as a p-type dopant in some semiconductors, and beryllium oxide is used as a high-strength electrical insulator and heat conductor. Beryllium alloys are used for mechanical parts when stiffness, light weight, and dimensional stability are required over a wide temperature range. Beryllium-9 is used in small-scale neutron sources that use the reaction Be + He (α) → C + n, th…

Calcium, strontium and barium react with water and form hydroxides and hydrogen gas. Strontium hydroxide and barium hydroxide are strong bases. Hydroxides of alkaline earth metals'' are basic. Also basic strength increases down the family. As an example, Strontium hydroxide (Sr (OH) 2) is more basic than Calcium hydroxide (Ca (OH) 2).

CONCEPT. The six alkaline earth metals — beryllium, magnesium, calcium, strontium, barium, and radium — comprise Group 2 on the periodic table of elements. This puts them beside the alkali metals in Group 1, and as their names suggest, the two families share a number of characteristics, most notably their high reactivity.

Solutions of alkali metals in liquid ammonia are intensely colored and good conductors of electricity due to the presence of solvated electrons (e −, NH 3 ), which are not attached to single atoms. A solvated electron is loosely associated with a cavity in the ammonia solvent that is stabilized by hydrogen bonds.
