uses of alkaline earth metals

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. 6) Magnesium also used for ignition of thermite charge in aluminothermy and for preparing Grignard’s reagent which are widely used in organic synthesis. iii. Magnesium is needed for DNA repair. The other alkali metals are much rarer. Decades later the use of radium ceased when people discovered the dangers of radiation. Uses of metals can be found in many ways in medicine. Radium was discovered by scientists Marie and Pierre Curie. Strontium, barium, and magnesium are key ingredients for a colorful and intense firework show. Shiny and soft, strontium forms compounds with oxygen and other oxides such as carbonate (CO3), nitrate (NO3), sulfate (SO4) and chlorate (ClO3). Francium is radioactive, and only minute amounts of it exist in nature. Scroll down to learn about the uses of alkali metals. Uses of alkaline earth metals Magnesium (Mg): It is the second most common cation in intracellular fluid. Today radium is used in the treatment of certain types of cancers. Like their very reactive neighbors in column 1A (the alkali metals), the alkaline earth metals don't often occur in their pure, unionized form. Mentzer graduated from Rutgers University with degrees in Anthropology and Biological Sciences. All alkaline earth elements have an oxidation Magnesium alloys with aluminum provide light weight and sturdy materials for airplanes, missiles, and rockets. The bright reds come from strontium salts and the greens come from bariu… Barium sulfate is commonly used to aid in using X-rays to detect problems in the digestive tract.

Uses of the Alkaline Earth Metals. Calcium is a key component in the structures of living things including bones, teeth, shells and exoskeletons. Elemental magnesium is the only alkaline earth metal that is produced on a large scale (about 5 × 10 5 tn per year). Calcium, strontium and barium can react with water at room temperature. Wow! 3) Magnesium (powder or ribbon)  is used in flash powders and bulbs, incendiary bombs and signals. The alkaline-earth metals were later produced by reduction of their salts with free alkali metals, and it was in this way (the action of … 1) It is used in the manufacture of alloys. Fig. Calcium plays an important role in helping us to build strong bones and magnesium is used to help regulate the body's temperature. Beryllium is useful in radiology because X-rays can pass through beryllium, making it appear transparent. Lithium is also used to make electrochemical cells. Chlorides and fluorides of alkali and alkaline earth metals are added to reduce the melting point. 3. Since magnesium burns readily in oxygen, the flow of a reducing gas like coal gas is maintained during electrolysis. They readily react with oxygen, which accepts electrons to form ions with a 2- charge. 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. M + 2 H C l → M C l 2 + H 2 ( M = Be, Mg, Ca, Sr, Ba ) Be is amphoteric in nature and dissolves in alkalies liberating H 2 … Ore compounds containing beryllium, aluminum and silicon can form green and bluish-colored gemstones such as emeralds, aquamarine and alexandrite. A suspension of magnesium hydroxide in water is known as milk of magnesia. This compound is insoluble in water and coats the esophagus, stomach and intestines when swallowed. Be is used in the manufacture of alloys. English chemist Sir Humphry Davy was the first to isolate many of the alkaline earth metals including calcium, strontium, magnesium, and barium. The next most common is potassium, which is 2.6 percent of Earth’s crust. Now we are going to discuss uses of each element in 2nd group. Rubidium, lithium, and cesium are 0.01, 0.002, and 0.0007 percent of Earth’s crust, respectively. Technology and Current Uses of Rubidium and Cesium 51 Part 2: Alkaline Earth Metals 53 Introduction to Alkaline Earth Metals 53 The Discovery and Naming of Alkaline Earth Metals 54 5 Beryllium 56 The Astrophysics of Beryllium 57 Beryllium on Earth 59 The Chemistry of Beryllium 61 Reducing the Critical Mass in Nuclear Weapons 62 Copper-beryllium alloys are used in the preparation of high strength springs. Alkaline earth metals are shiny, soft or semi-soft metals that are insoluble in water. It is often used to make X-ray tubes and windows. 3. 3. 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. 1. We use different types of metal every single day, from the frame of our cars to the silverware we typically use to eat lunch. Physical Properties Beryllium Magnesium Calcium Strontium Barium Radium The alkaline earth elements are metallic elements found in the second group of the periodic table. Alkaline earth metals humans body alkaline earth metals definition alkaline earth metals periodic table chemistry What Are The Properties Of Alkaline Earth MetalsAlkaline Earth Metals Definition Location In The Periodic Table6 Uses Of Alkaline Earth Metals In Daily Life Pounds AzChemical Families Patterns And Properties Form 2 Chemistry NotesAlkaline Earth Metals … 2. Radium is white in color and soft and shiny like the other alkaline earth metals. 3. The physical properties of magnesium are similar to beryllium. The resulting compounds are called oxides. 1) It is used to prepare alloy with aluminium , zinc , manganese and tin. As part of alkaline earth metal, Strontium (Sr) has appearance silvery – white, a shiny metal. FUNCTION: 1. Uses of alkaline earth metals . It is used as antacid, that is, for treating acidity. They are called so because the oxides of these metals are basic, and the metals are found inside the Earth’s crust. 3Ca + 2P → Ca 3 P 2. Uses of Alkaline Earth Metals; Define Alkaline Earth Metals. As an example, copper beryllium alloys are used in the preparation of high strength springs. Calcium is also an important substance for manmade structures because it is used to make plaster, cement, drywall and other building materials. In its elemental form, beryllium is a soft metal, silvery white in color. They are the constituents of alloy formation. Radium salts are used in radiotherapy. The sample holder in X-ray emission studies usually made of beryllium. It is used in thermonuclear reactions. Several antacids use magnesium hydroxide to neutralize excess stomach acid. The silvery, semi-soft metal easily forms compounds with both oxygen molecules and water. 1. 4) A suspension of magnesium hydroxide in water (called milk of magnesia) is used as antacid in medicine. Alkaline earth metals are highly reactive, and the activity of these metals increases moving down the group. Alkaline earth metals are placed in group 2 of the periodic table. Your email address will not be published. Everyday Uses of Alkaline Earth Metals. It is often used to make X-ray tubes and windows. In medicine. Salts derived from strontium compounds burn red and are used in fireworks and signal flares. 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. Cu-Be alloys are used in the preparation of high strength springs. All alkaline earth elements have an oxidation number of +2, making them very reactive. The positive and negative ions are attracted to each other, resulting in a bond that has a net charge of 0. For manufacturing of many alloys.
