Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined. Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts.
Properties, sources and uses of the element lead. Lead is an incredibly useful metal, but it is also toxic to humans. In fact, if we didn't have to worry about breathing in its dust or ingesting ...
Facts about the Discovery and History of the Lead Element Lead was discovered was discovered in Ancient times and used by the ancient Egyptians, Greeks, Romans and Chinese. Galena, lead sulfide, the ore it could easily be extracted from in open fires and was used widely for cosmetics by the Ancient Egyptians.
Lead in History. Lead was one of the earliest metals discovered by the human race and was in use by 3000 B.C. The ancient Romans used lead for making water pipes and lining baths, and the plumber who joins and mends pipes takes his name from the Latin word plumbum, meaning lead.
Lead (/ ˈ l ɛ d /) is a chemical element with symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air.
Alchemists believed lead to be the oldest metal and associated it with the planet Saturn. They spent a lot of time trying to "transmute" lead into gold. Lead is one of the elements which has an alchemical symbol, shown below (alchemy is an ancient pursuit concerned with, for instance, the transformation of other metals into gold).
History of Lead. Lead is a soft, malleable, ductile, bluish-white, dense metallic element, extracted chiefly from galena and found in ore with zinc, silver and copper. The original use of lead plumbs the depths of history. In fact, the oldest known lead article is a figurine found in Egypt that dates back to 4,000BC.
Lead has been mined for more than 6,000 years, and the metal and its compounds have been used throughout history. Small lead nuggets have been found in pre-Columbian Peru, Yucatan, and Guatemala. The Greeks mined lead on a large scale from 650 onwards and not only knew how to obtain the metal but how to covert this to white lead.
Lead is a relatively abundant element because it the endpoint of the decay schemes of many radioactive elements with higher atomic numbers. Because it's fairly easy to extract (for a metal), lead has been used since prehistoric time. Lead was readily available to common people in the Roman Empire, finding use in dishes, plumbing, coins, and ...
Lead: Lead, a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. 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.
