Uses of the Alkali Earth Metals As far as the uses of the group two elements and their compounds are concerned, there is a lot to be understood on that front. To prevent oxidation and to keep out moisture, potassium is stored in petroleum. These have low ionization enthalpy (heat evolved when an atom gets ionized). Some of the examples of these occurrences would be table salt, you may not realize this but sodium makes up almost all of the little grains. Lithium is found in number of pegmatitic minerals, clays, brines, oceans, and in all living things. Significantly, K+-contained layered MnO2 catalysts have been verified as strong candidates toward catalytic oxidation of formaldehyde (HCHO).

Two-dimensional (2D) layered MnO2 materials, composed of exotic electronic properties and accessible active sites with alkali metal ions, provide a comprehensive platform for developing catalysts with chemical modification. Alkali metals are elements that are not found in nature in a free state, but rather in the form of ionic compounds because these metals easily lose their valence electron and they are the most powerful reducing agents, Preparing of these metals involves the electrolysis of their molten (fused) halides. It is used in fertilizers. Sodium is produced by electrolysis of sodium chloride. If potassium level is not balanced it may lead to hyperkalemia or hypokalemia. Potassium plays a vital role in the proper functioning of our body. Cesium-137 is used in brachytherapy to treat cancers. Lithium batteries are packed with lot of energy as compared to other metals. Alkali metals have one electron in their outer shell, which is loosely bound. Although they are soft enough to cut with a knife, exposing a bright surface, the metals react with water and air and quickly tarnish, so the pure metals are stored in an inert atmosphere or under oil to prevent oxidation. The uses of these metals are extremely limited. These are just like Group 17 (Halogens) in a approach that, it attains noble gas configuration after shedding its valence electron. They are mostly not found in free nature as they react quickly and vigorously. 4) A suspension of magnesium hydroxide in water (called milk of magnesia) is used as antacid in medicine.

Lithium is used in: Batteries, in the form of lithium carbonate it is used … These metals have only one electron in their outer shell. Potassium maintains blood pressure and acidity levels in our body. This information is very interesting! This valence electron is much more weakly bound than those in inner shells. Rubidium : While this was one of the first metals discovered using a spectroscope, which is able to photograph a chemical’s “energy fingerprint,” there haven’t been many, if any, uses discovered for it. When the coating is cut off with a knife, the shiny metal will be clearly visible. Sodium hydroxide is used as oven cleaner. Alkali elements belong to s-block, including hydrogen. Luminant, colorful flame is produced by them when burned with oxygen. This gives them the largest atomic radii of the elements in their respective periods. They are highly reactive with water. Potassium chromate is used in the tanning of leather and in the manufacture of inks, gun powder, dyes, safety matches etc.. Potassium is essential for normal cell respiration and electrolyte function as 95% of our cells are made of potassium. The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. Potassium is the 19th element in the periodic table. Calcium is used in the extraction of metals from their oxides which are difficult to reduce with carbon. Except Lithium, other alkali elements are predominantly ionic. What uses have been found for the remaining three alkali metals? Francium is produced by bombarding thorium with protons or by bombarding radium with neutrons. Stored in a mineral oil solution. Alkali metals are used on daily without us even realizing it. It has relatively few commercial uses and pure metal is combined with other metals to form alloys. What's common between sodium and lithium? 2) Metallic beryllium is used for making Windows of X- ray tubes. 1) It is used in the manufacture of alloys. The properties of an element have periodic dependence on its atomic number but not on atomic weight. Sodium alone has few uses, but when used in combination with chlorine, forms common salt, which is commonly used as a flavor enhancer. Francium has the lowest electronegativity among all the known elements. Alkali Metals. Potassium turns gray on exposure to air. Uses of Alkaline Earth Compounds Since magnesium burns brightly, it is used in flares and fireworks. Another example would be that lithium is in glass, aluminum, batteries and magnesium. Because sodium remains liquid over a wide temperature range (97.8–883°C), it is used as a coolant in specialized high-temperature applications, such as nuclear reactors and the exhaust valves in high-performance sports car engines. Softness of the element down the group increases due to increasing atomic number because the metallic bond will decrease with increase in atomic size. 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. Potassium chloride is essential for the growth of plants. Class 11: Chemistry: The s‐block Elements: Uses of Alkaline Earth Metals. These are similar to Group 17 (Halogens) in a way that, it attains noble gas configuration after losing its valence electron. Uses of the Alkali Metals. Sodium was first produced through nuclear fusion in stars, by fusion of two carbon atoms. It also helps us in determining the expected outcome of a given … The largest application of sodium silicate solutions is a cement for producing cardboard.
