The alkaline earths possess many of the characteristic properties of metals.Alkaline earths have low electron affinities and low electronegativities.As with the alkali metals, the properties depend on the ease with which electrons are lost.The alkaline earths have two electrons in the outer shell. Magnesium burns so actively in air, for example, that it is often used in flares because of the brilliant white light it produces during combustion. Calcium is a key component in the structures of living things including bones, teeth, shells and exoskeletons. 1) It is used in the manufacture of alloys. The alkaline nature of these solutions provides this group of metals with its name. 2) Magnesium – aluminium alloy being light in mass are used in construction of aircrafts. 5) Magnesium hydroxide and magnesium carbonate are used in making toothpaste. Calcium is even more plentiful on Earth than magnesium. Alkylmagnesium halides (RMgX where R = hydrocarbon group and X = halogen) are used to synthetise organic compounds. The silvery, semi-soft metal easily forms compounds with both oxygen molecules and water. They are called so because the oxides of these metals are basic, and the metals are found inside the Earth’s crust. Beryllium increases the hardness of alloys that are used to make tools and watch springs. The other alkali metals are much rarer. Calcium and barium metals due to their reactivity towards oxygen and nitrogen at elevated temperature have often being used to remove last traces of air from vacuum tubes.
