Product Information

The percentage of an element produced in the top producing country. The higher the value, the larger risk there is to supply. Mercury was used inside wobbler lures. Its heavy, liquid form made it useful since the lures made an attractive irregular movement when the mercury moved inside the plug. Such use was stopped due to environmental concerns, but illegal preparation of modern fishing plugs has occurred. Sobernheim, Moritz (1987). "Khumārawaih". In Houtsma, Martijn Theodoor (ed.). E.J.

Cl) عند النظر للمجموعة، في المجموعات الأخيرة كل من الفلور (F) والبروم (Br). وبغض النظر أيضا عن اختلافها الكبير في الكتلة فإن لها خواص متقاربة للغاية. فهي جميعا عناصر تساعد على التآكل بشدة (أي أنها ترتبط بسرعة مع الفلزات لتكون أملاح هاليدات الفلز)، الكلور والفلور غازات، ولكن البروم سائل له درجة غليان منخفضة للغاية، كما أن الكلور والبروم لهما لون.

It has a freezing point of −38.83°C and a boiling point of 356.73°C, [10] [11] [12] both the lowest of any stable metal, although preliminary experiments on copernicium and flerovium have indicated that they have even lower boiling points. [13] This effect is due to lanthanide contraction and relativistic contraction reducing the radius of the outermost electrons, and thus weakening the metallic bonding in mercury. [10] Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69g/cm 3 when liquid to 14.184g/cm 3 when solid. The coefficient of volume expansion is 181.59 × 10 −6 at 0°C, 181.71 × 10 −6 at 20°C and 182.50 × 10 −6 at 100°C (per°C). Solid mercury is malleable and ductile and can be cut with a knife.

The Fresnel lenses of old lighthouses used to float and rotate in a bath of mercury which acted like a bearing. [80]Owing to its acoustic properties, mercury was used as the propagation medium in delay-line memory devices used in early digital computers of the mid-20th century. a b Greenwood, Norman N.; Earnshaw, Alan (1997).

Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. [9]Norway enacted a total ban on the use of mercury in the manufacturing and import/export of mercury products, effective 1 January 2008. [141] In 2002, several lakes in Norway were found to have a poor state of mercury pollution, with an excess of 1μg/g of mercury in their sediment.

Gaseous mercury is used in mercury-vapor lamps and some " neon sign" type advertising signs and fluorescent lamps. Those low-pressure lamps emit very spectrally narrow lines, which are traditionally used in optical spectroscopy for calibration of spectral position. Commercial calibration lamps are sold for this purpose; reflecting a fluorescent ceiling light into a spectrometer is a common calibration practice. [70] Gaseous mercury is also found in some electron tubes, including ignitrons, thyratrons, and mercury arc rectifiers. [71] It is also used in specialist medical care lamps for skin tanning and disinfection. [72] Gaseous mercury is added to cold cathode argon-filled lamps to increase the ionization and electrical conductivity. An argon-filled lamp without mercury will have dull spots and will fail to light correctly. Lighting containing mercury can be bombarded/oven pumped only once. When added to neon filled tubes the light produced will be inconsistent red/blue spots until the initial burning-in process is completed; eventually it will light a consistent dull off-blue color.
