Periodic Table Of Elements Chart

Chemical calcium (Ca) is one of the alkaline-earth metals of group 2 (IIa) of the periodic table. It is the most abundant metal in the human body and the fifth most abundant element on earth.

Calcium does not occur naturally in the free state, but its elemental compounds are widely distributed. Lime (calcium oxide, CaO), a calcium compound, was widely used by ancient people. Silver, a soft and light metal, was first isolated by Sir Humphrey Davy after purifying mercury from an amalgam made by electrolysis of lime and mercuric oxide. The name of the ingredient comes from the Latin word for lime.

Calcium makes up 3.64 percent of the Earth’s crust and 8 percent of the Moon, and its cosmic abundance is estimated to be 4.9 × 10.

Atom). Calcite (calcium carbonate) is found on earth in limestone, limestone, marble, dolomite, eggshell, perile, corals, stalactites, stalagmites, and animal shells. many of the sea. Calcium carbonate deposits dissolve in water containing carbon dioxide to form calcium bicarbonate, Ca (HCO).

. This process often leads to the formation of caves, where limestone is embedded in the form of stalactites and stalagmites. Calcium hydroxyl phosphate is the main component of teeth and bones and occurs as the mineral apatite. In the case of calcium fluoride, it occurs as fluorite or fluorspar. Calcium sulfate is formed as anhydrite. Calcium is found in many other minerals, including aragonite (a form of calcium carbonate) and gypsum (a form of calcium sulfate), as well as many feldspars and zeolites. It is abundant in the form of silicates and aluminosilicates in salt deposits and natural waters, including the sea.

Pure calcium iron, formerly obtained by electrolysis of anhydrous calcium chloride, is now produced by heating lime with aluminum. The metal reacts slowly with oxygen, water vapor, and nitrogen in the air to form yellow coatings of oxides, hydroxides, and nitrides. It oxidizes by heating in air or pure oxygen and reacts with hot water (and gradually with cold water) to form hydrogen gas and calcium hydroxide. When heated, calcium absorbs hydrogen, halogen, boron, sulfur, carbon, and phosphorus. Although it is positive compared to sodium as a reducing agent, calcium is more expensive and less effective than the latter. However, in many processes of oxidation, reduction, and degassing, calcium is used to prepare chromium, thorium, uranium, zirconium, and other metals from their oxides due to their low volatility.

Iron itself is used as an alloy of aluminum, copper, lead, magnesium and other base metals; as an oxidizing agent in mixtures at certain high temperatures; and as a getter in electron tubes. A small percentage of calcium is used in many alloys for special purposes. For example, it is mixed with lead (0.04 percent calcium) and is used as a sheath for telephone cables and as a grid for permanent type batteries. Adding 0.4 to 1 percent of alloys-based alloys improves the biological resistance of orthopedic implants to damage and allows complete tissue healing before the implant loses structural integrity.

Natural calcium consists of a mixture of six isotopes: calcium-40 (96.94 percent), calcium-44 (2.09 percent), calcium-42 (0.65 percent), and calcium-48 small and 43. calcium-46. Calcium-48 undergoes beta decay twice with a half-life of about 4×10.

Year, so it is stable for all practical purposes. It is richer in neutrons and is used to create heavy nuclei in particle accelerators. The radioactive isotope calcium-41 is produced in small amounts on Earth by the natural bombardment of calcium-40 by neutrons in cosmic rays.

Calcium is essential to plant and animal life and is widely used as a signal transducer, enzyme cofactor, and structural component (eg, cell membranes, bones, and teeth). Many organisms store calcium in their shells or bones, and calcium is the most abundant in higher animals. Most important deposits of carbonate and phosphate are of organic origin.

2 percent of calcium in the human body. The main sources of calcium in the human diet are milk, dairy products, fish and green vegetables. Rickets occurs when vitamin D deficiency causes an inability to absorb calcium from the gastrointestinal tract in the extracellular fluid. This disease mainly affects babies and children. Both metals and metalloids are part of the periodic table, but the difference between them can be recognized based on their properties. There are three types of elements in the periodic table; Metals, non-metals and metalloids. Most elements are elements and very few are metalloids. The main difference between metals and metalloids can be clearly explained when we look closely at their properties. Steels have unique metallic properties such as luster, high density, melting point, and electrical conductivity. However, metalloids have properties of metals and non-metals. Metals are on the left side of the periodic table, while metalloids are between metals and nonmetals.

About 75% of the elements in the periodic table are metals. They are classified in the periodic table according to common characteristics; Actinide metals, lanthanide metals, alkali metals, alkali-elements, rare metals, rare earth metals, transition metals. Some metals, such as gold and silver, are very valuable because of their abundance in the earth. Metals have special properties such as metallic luster, electrical and thermal conductivity, high melting point, and reactivity with other materials. Some metals form alloys with other metals; They are very useful for business applications.

Metalloids The metallic line in the periodic table separates the metals (on the left side of the periodic table) from the non-metals (on the right side of the periodic table). They show signs of metals and non-metals. For example, a metalloid can be shiny like a metal or dull like a nonmetal. Metalloids such as silicon and germanium are semiconductors under special conditions; Therefore, they are very useful in many business applications.

Metalloids are intermediate between metals and nonmetals. In other words, some metalloids are metals while others are non-metals.

Most metals are highly reactive and quickly oxidize when exposed to air, forming a layer on the surface of the metal. Metal oxides are basic and sweet.

Silicon is a very poor conductor of heat and electricity. But silicon and germanium are the best miconductors, which means they conduct electricity under special conditions. Therefore, these materials are used for the manufacture of computers and calculators.

Metals: Metals are used in many areas depending on their properties; They are used in tableware, jewelry, electronics, engineering and construction materials, machinery, electrical cables, and to a lesser extent, pharmaceuticals and food products.

Metalloids: Metalloids are very valuable in the semiconductor industry because of their unique conductive properties (conducting electricity only partially under certain conditions).

He studied human resource development in engineering and has over 10 years of experience in content development and management. In this tutorial, you will learn about the periodic table of elements, their properties, metals and metals.

Most of the elements in the periodic table are classified as metals. The metals in the periodic table are to the left of the zigzag line through the five elements: boron, silicon, arsenic, tellurium, and astatine. Elements to the right or left of the line (boron, silicon, germanium, arsenic, tellurium, antimony, polonium) can be classified as metalloids and semimetals. This means they have both metallic and non-metallic properties.

Other popular metals on the periodic table include: iron, lead, aluminum, silver, calcium, and sodium, which exist as solids at room temperature. Classified as a metal, mercury is the only metal in the periodic table that occurs as a liquid. Gold is the softest of the eighteen metals on the periodic table. Therefore, jewelry can never be 100% pure gold, otherwise it will not withstand daily wear and tear.

The elements are on the left side of the periodic table, so they have the lowest ionization energy
