what do all alkaline earth metals have in common?
157265
The alkaline earth metals are all of the elements in the second column (column 2A) of the periodic table. This group includes beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Alkaline earth metals have only two electrons in their outermost electron layer.

Answer and Explanation: The alkaline earth metals have two valence electrons.

Group 2: Alkaline Earth Metals Alkaline Earth metals are silvery grey in color. They are harder and denser than the alkali metals. All are solids at room temperature. The alkaline Earth metals make up group 2 of the periodic table.

Key Points. 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.

Some of the groups have widely-used common names, including the alkali metals (Group 1) and the alkaline earth metals (Group 2) on the far left, and the halogens (Group 17) and the noble gases (Group 18) on the far right. The elements can be broadly divided into metals, nonmetals, and semimetals.

The alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive.
417445
The elements in group one of the periodic table (with the exception of hydrogen - see below) are known as the alkali metals because they form alkaline solutions when they react with water. ... The elements in this group, which are all shiny and silvery-white in appearance, are known as the alkaline earth metals.

They are silvery or gray in color. They are also relatively soft and low in density. 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 alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive. Because of their reactivity, the alkaline metals are not found free in nature.

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).

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.

The alkaline earth metals are all of the elements in the second column of the periodic table. This group includes beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

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.
1291238
Magnesium. Magnesium (symbol Mg) is an alkaline earth metal and has common oxidation number +2.

Reactions of Alkaline Earth Metals All the alkaline earth metals except beryllium also react with water to form strongly alkaline hydroxides which should be handled with great care. The heavier alkaline earth metals react more vigorously than the lighter ones.

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.
