Several antacids use magnesium hydroxide to neutralize excess stomach acid. Like their very reactive neighbors in column 1A (the alkali metals), the alkaline earth metals don't often occur in their pure, unionized form. Barium is also an ingredient in paint pigments. Beryllium is useful in radiology because X-rays can pass through beryllium, making it appear transparent. 3. All alkaline earth elements have an oxidation Francium is radioactive, and only minute amounts of it exist in nature. 5.2 Alkali metals: The word “alkali” is derived from the word al-qalÄ«y meaning the plant ashes, referring to the original source of alkaline substances. The general outer electronic configuration of alkaline earth metal is ns 2. For example with lead it is used to make ‘white metal’ bearings for motor engines, with aluminium to make aircraft parts, and with magnesium to make armour plates. They are generally harder and less reactive than the metals in in group IA, such as sodium, and are softer and more reactive than the metals in group IIIA, such as aluminum. Calcium, strontium and barium can react with water at room temperature. Magnesium is one of the most plentiful elements found in the Earth’s crust and is a key component in chlorophyll, the substance in green plants used in photosynthesis. Uses of beryllium .

Calcium and magnesium ions are an important component of human nutrition; calcium ions are necessary for healthy bones and teeth and magnesium ions are necessary for metabolism and muscle function. Learn the basics about Alkaline Earth Metals, their uses and chemical properties. Soon after its discovery by the Curies in the late 1800s, radium was used for medical therapies and to make glow-in-the-dark clocks and watches. Metals are available as micro-elements in our bodies. The next most common is potassium, which is 2.6 percent of Earth’s crust. Uses of the Alkaline Earth Metals. alkali and alkaline earth metals respectively. As an example, copper beryllium alloys are used in the preparation of high strength springs. Uses of Alkaline Earth Compounds Since magnesium burns brightly, it is used in flares and fireworks. Since magnesium burns readily in oxygen, the flow of a reducing gas like coal gas is maintained during electrolysis. 2) Magnesium – aluminium alloy being light in mass are used in construction of aircrafts. Alkaline earth metals are shiny, soft or semi-soft metals that are insoluble in water. Alkaline earth metal phosphide are given when heat is supplied. Properties of the Alkaline Earth Metals . Fig. It is often used to make X-ray tubes and windows. The physical properties of magnesium are similar to beryllium. The other alkali metals are much rarer. Calcium is a key component in the structures of living things including bones, teeth, shells and exoskeletons. Mg-Al alloys are used in construction of aircrafts. Scroll down to learn about the uses of alkali metals. Alkaline earth metals are placed in group 2 of the periodic table. In its elemental form, beryllium is a soft metal, silvery white in color. 2. Decades later the use of radium ceased when people discovered the dangers of radiation. 5) Magnesium hydroxide and magnesium carbonate are used in making toothpaste. It is used as antacid, that is, for treating acidity. So metals are available as trace elements in the food we eat and water we drink. Uses of alkaline earth metals . Beryllium is used for manufacturing of parts of X-ray tubes. 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. Mentzer graduated from Rutgers University with degrees in Anthropology and Biological Sciences. 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. The properties of an element have periodic dependence on its atomic number but not on atomic weight. Physical Properties Beryllium Magnesium Calcium Strontium Barium Radium The alkaline earth elements are metallic elements found in the second group of the periodic table. The Alkaline-Earth Metal Family What are Alkaline Metals? Beryllium is useful in radiology because X-rays can pass through beryllium, making it appear transparent. It moderates cellular differentiation and proliferation and improves tissue sensitivity to circulating insulin. Chlorides and fluorides of alkali and alkaline earth metals are added to reduce the melting point. The sample holder in X-ray emission studies usually made of beryllium. Group 2 elements are known as Alkaline Earth Metals. Alkaline earth metals also react vigorously with oxygen. In compounds, alkaline earth metals lose two electrons, forming ions with a 2+ charge. Unlike the transparency of beryllium, X-rays cannot penetrate barium. The silvery, semi-soft metal easily forms compounds with both oxygen molecules and water. ALKALINE EARTH METALS Also called as Group II A elements. Elemental magnesium is the only alkaline earth metal that is produced on a large scale (about 5 × 10 5 tn per year). Because of their reactivity, the alkaline earth metals are not found free in nature. Alkaline earth metals have low electrode potentials, and so are obtained by the electrolysis of the fused chlorides. Ore compounds containing beryllium, aluminum and silicon can form green and bluish-colored gemstones such as emeralds, aquamarine and alexandrite. They are needed for conduction of nerve impulses, to carry oxygen by blood, to facilitate enzyme reactions, and more. It doesn’t react with water at room temperature, but readily reacts with acids. The positive and negative ions are attracted to each other, resulting in a bond that has a net charge of 0. They readily react with oxygen, which accepts electrons to form ions with a 2- charge.
