Alkaline earth metals Magnesium shows insignificant reaction with water, but burns vigorously with steam or water vapor to produce white magnesium oxide and hydrogen gas: Mg(s) + 2 H2O(l) ⟶ Mg(OH)2(s) + H. A metal reacting with cold water will produce metal hydroxide.

Alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

All of the alkaline earth metals, except magnesium and strontium, have at least one naturally occurring radioisotope: beryllium-7, beryllium-10, and calcium-41 are trace radioisotopes. Calcium-48 and barium-130 have very long half-lives and thus occur naturally. All isotopes of radium are radioactive.

Alkali metals are water soluble. ... All the alkali metals react vigorously with cold water. In each reaction, hydrogen gas is given off and the metal hydroxide is produced.
875154
Reactions with Group 2 Elements The elements of Group 2 are beryllium, magnesium, calcium, strontium, barium, and radioactive radium. ... Similarly to Group 1 oxides, most group 2 oxides and hydroxides are only slightly soluble in water and form basic, or alkaline solutions.

Reactivity of Alkaline Earth Metals All alkaline Earth metals have similar properties because they all have two valence electrons. They readily give up their two valence electrons to achieve a full outer energy level, which is the most stable arrangement of electrons.

All other group 2 metals Except beryllium, the other alkaline earth metals form oxides in air at room temperature.

Alkaline earth metals Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if metal is heated to red heat. Additionally, beryllium has a resistant outer oxide layer that lowers its reactivity at lower temperatures.
282566
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.

It's a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.

Interesting Facts about Alkaline Earth Metals The name "alkaline earths" comes from an old name for the oxides of the elements. They are called alkaline because they form solutions with a pH greater than 7, making them bases or "alkaline." Radium is formed from the decay of uranium.

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.

The periodic trend in the solubility of alkaline earth metal compounds is that as one goes down a group, it increases in activity. For example, barium has more activity than strontium or calcium.
187453
In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides. ... The second ionization energy of all of the alkaline metals is also somewhat low. Beryllium is an exception. It does not react with water or steam, and its halides are covalent.
1270933
Similarly, all the alkaline earth metals react with the heavier group 15 elements to form binary compounds such as phosphides and arsenides with the general formula M3Z2. Higher lattice energies cause the alkaline earth metals to be more reactive than the alkali metals toward group 15 elements.
944926
The hydroxides of the alkali metals, lithium, sodium, potassium, rubidium, and cesium, are the strongest bases and the most stable and most soluble of the hydroxides. ... Calcium, barium, and strontium—all alkaline earth metals—form soluble hydroxides that are strong bases but are less stable than the alkali hydroxides.

Alkaline water contains alkaline minerals like calcium, magnesium, and potassium. Ionized water contains minerals having an electrical charge. Alkaline water has high alkalinity while pH level is moderate whereas Alkalinity of Ionized water can be adjusted according to the needs of the body through water ionizers.
