Lead <---Thallium Bismuth---> Symbol: Pb Atomic Number: 82 Atomic Weight: 207.2 Classification: Post-transition metal Phase at Room Temperature: Solid Density: 11.34 grams per cm cubed Melting Point: 327.5°C, 621.4°F Boiling Point: 1749°C, 3180°F Discovered by: Known about since ancient times Lead is the fifth element of the fourteenth column in the periodic table. It is classified as a post-transition metal, a heavy metal, and a poor metal. Lead atoms have 82 electrons and 82 protons with 4 valence electrons in the outer shell. Characteristics and Properties Under standard conditions lead is a soft silvery metal with a bluish tint. It becomes a darker gray after coming into contact with air. It is very malleable (can be pounded into a thin sheet) and ductile (can be stretched into a long wire). Lead is a poor electrical conductor when compared to other metals. Lead is a very heavy element. It combines with other elements to make a variety of minerals including galena (lead sulfide), anglesite (lead sulfate), and cerussite (lead carbonate). Where is it found on Earth? Lead can be found in the Earth's crust in its free form, but it is mostly found in ores with other metals such as zinc, silver, and copper. Even though there isn't a high concentration of lead in the Earth's crust, it is fairly easy to mine and refine. How is lead used today? The majority of lead produced today is used in lead-acid batteries. These types of batteries are used in cars because of their low cost and high power. Because lead is resistant to corrosion, has such a high density, and is relatively inexpensive, it is used in water applications such as weights for scuba divers and ballasts for sailboats. Other applications that use lead include roofing material, electrolysis, statues, solder for electronics, and ammunition.
