Skin and eye contact can cause severe burns leading to permanent damage. Vitamin K (from the Danish word koagulation) is required for the synthesis of several blood clotting factors, including prothrombin and factors VII, IX, and X. the end of the formula. Potassium chlorate (KClO3) is added to matches and explosives. Weird & Wacky, Copyright © 2020 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company. Atomic mass Density (near r.t.) Melting point Boiling point Year of discovery Discoverer; Ac: Actinium: 89: 227,0278 g/mol Standard Reference Data Act. Potassium can be found in vegetables, fruit, potatoes, meat, bread, milk and nuts. In all cases it is the negative anion, not the potassium, which is the key to their use. chosen may not be the desired one. [16], Metallic potassium is used in several types of magnetometers.[120]. Chemical sym Name Origin of symbol Atomic No. Atomic Mass: 39.0983 amu. Potassium is from the mineral carnallite and is often used in making glass and soap. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential. Species with two C, zero or more H and one or more F. Select any desired options for the search: Select the desired units for thermodynamic data: Enter a sequence of element symbols followed by numbers In humans, deficiency may occur following the administration of certain drugs that inhibit the growth of the vitamin-synthesizing bacteria or as a result of disorders affecting the production or flow of bile, which itself is necessary for the intestinal absorption of vitamin K. In newborn infants, the absence of intestinal bacteria, low levels of vitamin K in the mother’s milk, or the absence of body stores of vitamin K may result in bleeding, which can be prevented by the administration of vitamin K to the infant shortly after birth. Oxygen, carbon and hydrogen are found in water and air; secondary nutrients that plants need include magnesium, calcium and sulfur. It is mediated by a, The ion transport system moves potassium across the cell membrane using two mechanisms. Number of Neutrons: 20. Copyright for NIST Standard Reference Data is governed by Each chemical symbol represents an abbreviation for the chemical element's name. In the case of potassium, the letter "K" represents it on the Periodic Table. element, use an asterisk (*) after the element symbol. and Informatics.

The other is passive and allows potassium to leak out of the cell. the number after the element symbol. Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite. In the case of potassium, the letter "K" represents it on the Periodic Table. Some Class D dry powder extinguishers designed for metal fires are also effective. McNaught, A. D. and Wilkinson,A. TRY3STEPS.COM: We ask you, humbly: don't scroll away. If correct case is not used, the formula may be ambiguous and the interpretation chosen may not be the desired one. If the charge is greater than Megatons of these compounds are produced annually. Most come from the Latin name for the chemical. The main mining area used to be Germany, which had a monopoly of potassium before the first World War. Technology, Office of Data We don't have salespeople. This is probably initiated by gut cell potassium receptors that detect ingested potassium and trigger, The predictive or circadian system increases renal secretion of potassium during mealtime hours (e.g. When our kidneys are somehow malfunctioning an accumulation of potassium will consist. The name for the element comes from the Latin word "kalium." Because its density is 0.89 g/cm3, burning potassium floats in water that exposes it to atmospheric oxygen. Vitamin K, any of several fat-soluble naphthoquinone compounds. [124], Ingestion of large amounts of potassium compounds can lead to hyperkalemia, strongly influencing the cardiovascular system. Are We Wrong To Think We're Right? daytime for humans, nighttime for rodents) independent of the presence, amount, or absence of potassium ingestion. To specify one or more of a given atom, use a When a vitamin is in short supply or is not able to be utilized properly, a specific deficiency syndrome results.

A very few elements have symbols which appear to have no relationship with their names.
