Calcio

Descripción:
Calcio, con el símbolo químico Ca y el número CAS 7440-70-2, es un metal alcalinotérreo que es esencial para varios procesos biológicos e industriales. Es un metal blando de color blanco plateado que es relativamente reactivo, particularmente con agua y ácidos, formando hidróxido de Calcio y gas hidrógeno. En su forma elemental, Calcio se encuentra típicamente en la naturaleza como parte de compuestos, como el carbonato de Calcio en la piedra caliza y el sulfato de Calcio en el yeso. Tiene un punto de fusión de aproximadamente 842 grados Fahrenheit (450 grados Celsius) y un punto de ebullición de aproximadamente 1,470 grados Fahrenheit (800 grados Celsius). Calcio juega un papel crucial en los sistemas biológicos, particularmente en la formación de huesos y dientes, así como en la contracción muscular y la función nerviosa. En aplicaciones industriales, se utiliza en metalurgia, como agente reductor en la extracción de otros metales, y en la producción de cemento y cal. Debido a su reactividad, Calcio debe almacenarse bajo aceite o en una atmósfera inerte para prevenir la oxidación.

    CAS:
    <p>Calcium is a chemical element with the symbol Ca and atomic number 20. It has an atomic weight of 40.078, which means that it is 40.078 times heavier than hydrogen. Calcium is an alkaline earth metal, as are magnesium and barium. Calcium is classified as a hard metal because it has a high melting point and its oxide layer resists corrosion by water and air. The ionized form of calcium (Ca2+) may be found in the cytosol, or in transport vesicles in muscle cells or other types of cells such as those of the intestine or bone cells. The main biological role of calcium ions is to maintain the potential difference across excitable cell membranes, enabling normal nerve transmission and muscle contraction, including the contraction of heart muscles. The concentration of calcium ions in extracellular fluid is tightly regulated by the kidneys under instruction from parathyroid hormone (PTH) and calcitonin hormones to keep blood calcium levels within a narrow range</p>
