which element is not an alkaline earth metal?
3335
Nuclear stability. Of the six alkaline earth metals, beryllium, calcium, barium, and radium have at least one naturally occurring radioisotope; magnesium and strontium do not.
133778
All other group 2 metals Except beryllium, the other alkaline earth metals form oxides in air at room temperature.
618540
Alkaline earth metals react with halogens and (except for beryllium) with water and oxygen. Magnesium, being less reactive, reacts only at higher temperatures than the other alkaline earth metals. ... Salts of beryllium are toxic, and water-soluble or acid-soluble salts of barium are toxic.

Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common. They are: dull (not shiny)

The elements in Group 2 (beryllium, magnesium, calcium, strontium, barium, and radium) are called the alkaline earth metals (Figure below). These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is ns2.

The most common alkali metal is sodium, which is 2.8 percent of Earth's crust. The most common sodium compound is sodium chloride (NaCl), salt. The next most common is potassium, which is 2.6 percent of Earth's crust. The other alkali metals are much rarer.

You will find the alkaline earth metals right next door in Group II. This is the second most reactive family of elements in the periodic table. Do you know why they are called alkaline? When these compounds are mixed in solutions, they are likely to form solutions with a pH greater than 7.

Alkaline-earth metal. ... 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).

Alkaline Earth Metals. The alkaline earth metals are the elements that correspond to group 2 of the modern periodic table. This group of elements includes beryllium, magnesium, calcium, strontium, barium, and radium. ... The general electronic configuration of these elements is ns2.

Beryllium (Be), the smallest alkaline earth metal, is atomic number 4 on the periodic table, has an atomic weight of 9.01 amu (atomic mass unit), and melting and boiling points of 2, 348.6°F (1, 287°C) and about 4, 479.8°F (2, 471°C), respectively.

The name comes from the fact that the oxides of these metals produced basic solutions when dissolved in water, and they remained solids at the temperatures available to the ancient alchemists. Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form.
852801
Alkali metals are the elements in group 1 of the periodic table. Alkaline earth metals are the elements in group 2 of the periodic table. Both show basic properties. ... The main difference between alkaline and alkali is that alkali metals have one valence electron, whereas alkaline earth metals have two valence electrons.
1270911
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.
934072
The alkaline earth metals have two valence electrons. The alkaline earth metals are in the second family on the periodic table. It is a main group...
