Pb-208 has also been used to study the configuration of neutron stars.

It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. Lead (pronounce: "/'lɛd/") is a chemical element. Where did lead get its name? These uses have been reduced recently because of environmental concerns about cumulative lead poisoning.Lead is also used in cable covering, as ammunition, as electrodes, in solder and as roofing material.The image below shows shiny, untarnished lead balls.Lead is extremely resistant to corrosion and is a poor conductor of electricity.Lead is a bluish-gray, soft, dense metal that has a bright luster when freshly cut.For online linking, please copy and paste one of the following:Lead has been known since ancient times.

Isotopes Lead occurs naturally in the form of four isotopes.

Argon. The Romans also used lead for plumbing.It tarnishes slowly in moist air to form a dull gray coating.Historically, lead was used in plumbing.Nasa: A cargo tag made of lead was unearthed during excavation of the original colony at Jamestown, Virginia. . Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.Native lead is rare in nature. Lead is very malleable, ductile, and dense and is a poor conductor of electricity. Known in antiquity and believed by the alchemists to be the oldest of metals, lead is highly durable and resistant to corrosion. Silver. World production of new lead is 6 million tonnes a year, and workable reserves total are estimated 85 million tonnes, which is less than 15 year's supply. To cite this page in an academic document, please use the following MLA compliant citation:The metal is used as shielding from radiation, e.g. It is believed to have made the trip from England in 1611.Its ores are widely distributed and it has a low melting point so it is easily smelted.Lead oxide is also used in the manufacture of fine crystal glass. The element name "lead" comes from the Anglo-Saxon word for the metal. Natural lead consists of a mixture of 4 stable isotopes, although radioisotopes also exist. The symbol for the element lead is Pb, for plumbum, which comes from Latin for lead. For more effects on freshwater ecosystem take a look at lead in freshwater. Lead is a considered a basic metal or post-transition metal. Lead (/ ˈ l ɛ d /) is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. Lead is an Anglo-Saxon word for the metal that has been used and known about since ancient times. Its atomic number is 82, atomic mass is 207.2 and has a melting point of 327.8°C. It is a heavy metal that is denser than most common materials. Aluminum. The symbol for the element lead is Pb, for plumbum, which comes from Latin for lead. The symbol Pb comes from the Latin word for lead, "plumbum."

Americium. Lead affects the gut, central nervous system and causes anaemia.Binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and other compounds of lead where known.Bond strengths; lattice energies of lead halides, hydrides, oxides (where known); and reduction potentials where known.Lead isotopes are used for medical and scientific purposes. Lead, a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. Lead is a particularly dangerous chemical, as it can accumulate in individual organisms, but also in entire food chains. Its atomic number is 82, atomic mass is 207.2 and has a melting point of 327.8°C. Common Chemistry is helpful to non-chemists who know either a name or CAS Registry Number ® of a common chemical and want to pair both pieces of information. Its chemical symbol is Pb, which comes from plumbum, the Latin word for lead. in x-ray rooms and nuclear reactors.The chemical element lead is classed as an other metal. Lead: history Lead was discovered by known since ancient times in unknown at not known.
