Barium is also an ingredient in paint pigments. DISCOVERY : 1939, by Marguerite Perey of France NO USES KNOWN 13. Several antacids use magnesium hydroxide to neutralize excess stomach acid. 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. Beryllium increases the hardness of alloys that are used to make tools and watch springs. The general outer electronic configuration of alkaline earth metal is ns 2. In its elemental form, beryllium is a soft metal, silvery white in color. In medicine. 4) A suspension of magnesium hydroxide in water (called milk of magnesia) is used as antacid in medicine. Uses of alkaline earth metals Magnesium (Mg): It is the second most common cation in intracellular fluid. Copper – Beryllium alloys are used for manufacturing high strength springs. 2) Metallic beryllium is used for making Windows of X- ray tubes. It moderates cellular differentiation and proliferation and improves tissue sensitivity to circulating insulin. 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. Shiny and soft, strontium forms compounds with oxygen and other oxides such as carbonate (CO3), nitrate (NO3), sulfate (SO4) and chlorate (ClO3). Calcium is a key component in the structures of living things including bones, teeth, shells and exoskeletons. 1. Scroll down to learn about the uses of alkali metals. They are the constituents of alloy formation. Strontium, barium, and magnesium are key ingredients for a colorful and intense firework show. Barium sulfate is commonly used to aid in using X-rays to detect problems in the digestive tract. 3. Last Updated on May 3, 2020 By Mrs Shilpi Nagpal 4 Comments. Barium nitrate and barium chlorate are used in fireworks to give off green light when heated. However, its radioactivity sets it apart from the rest of its group. Uses of beryllium .

Properties of the Alkaline Earth Metals . The alkaline earth metals are produced for industrial use by electrolytic reduction of their molten chlorides, as indicated in this equation for calcium: (21.3.2) C a C l 2 (l) → C a (l) + C l 2 (g) The group 2 metal chlorides are obtained from a variety of sources. 1) It is used in the manufacture of alloys. Unlike the transparency of beryllium, X-rays cannot penetrate barium. 5) Magnesium hydroxide and magnesium carbonate are used in making toothpaste. 3) Magnesium (powder or ribbon)  is used in flash powders and bulbs, incendiary bombs and signals. Alkaline earth metals are placed in group 2 of the periodic table. They readily react with oxygen, which accepts electrons to form ions with a 2- charge. Alkaline earth metals have low electrode potentials, and so are obtained by the electrolysis of the fused chlorides. 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. They exist in +2 oxidation states. Magnesium-aluminum alloys are used for air craft construction. The bright reds come from strontium salts and the greens come from bariu… We use different types of metal every single day, from the frame of our cars to the silverware we typically use to eat lunch. Uses of Alkaline Earth Compounds Since magnesium burns brightly, it is used in flares and fireworks. Because of its low atomic number and very low absorption for X-rays, it is used as radiation windows for X-ray tubes and X-ray detectors. Alkaline earth metals also react vigorously with oxygen. Beryllium is used for manufacturing of parts of X-ray tubes. 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. Calcium is used in the extraction of metals from their oxides which are difficult to reduce with carbon. Since magnesium burns readily in oxygen, the flow of a reducing gas like coal gas is maintained during electrolysis. Calcium plays an important role in helping us to build strong bones and magnesium is used to help regulate the body's temperature. Calcium is also an important substance for manmade structures because it is used to make plaster, cement, drywall and other building materials. Lithium is also used to make electrochemical cells. iii. It is used in thermonuclear reactions. Everyday Uses of Alkaline Earth Metals. Mg is used to prepare alloys with Al, Zn, Mn and Sn.

English chemist Sir Humphry Davy was the first to isolate many of the alkaline earth metals including calcium, strontium, magnesium, and barium. … Francium is radioactive, and only minute amounts of it exist in nature. They are needed for conduction of nerve impulses, to carry oxygen by blood, to facilitate enzyme reactions, and more. Radium is white in color and soft and shiny like the other alkaline earth metals. alkali and alkaline earth metals respectively. Radium was discovered by scientists Marie and Pierre Curie. Combustion of magnesium yields a bright, white, long-lasting flame, making it useful in fireworks and flares. Like their very reactive neighbors in column 1A (the alkali metals), the alkaline earth metals don't often occur in their pure, unionized form. 3. As part of alkaline earth metal, Strontium (Sr) has appearance silvery – white, a shiny metal. About Mrs Shilpi Nagpal Decades later the use of radium ceased when people discovered the dangers of radiation. 3.
