It is classified as a <strong>post-transition metal<\/strong> and is one of the heaviest elements.<\/p>\n<p>Lead is a soft, <strong>malleable metal<\/strong> with a dull gray appearance. It is found in Group 14 of the periodic table, along with other metals such as carbon, silicon, and tin.<\/p>\n<p>Lead is a highly toxic substance that can have adverse effects on human health, especially in high doses. However, it also has various practical applications due to its unique properties, including its <strong>low melting point, high density, and resistance to corrosion<\/strong>.<\/p>\n<p>Despite the hazards associated with lead, it continues to be widely used in various industries, including construction, batteries, and ammunition.<\/p>\n<p style=\"text-align: center;\"><strong>Also Check: <a href=\"https:\/\/infinitylearn.com\/surge\/science\/speed-and-velocity\/\" target=\"_blank\" rel=\"noopener\">Speed and Velocity<\/a><\/strong><\/p>\n<p><strong>Key Properties of Lead<\/strong><\/p>\n<p>Lead is a bluish-white metal that is known for its malleability and ductility. It is a soft, heavy, and dense element, with a density of 11.34 grams per cubic centimeter. Its melting point is 327.5\u00b0C, and its boiling point is 1749\u00b0C.<\/p>\n<p>One of the most notable properties of lead is its <strong>low electrical conductivity<\/strong>. This makes it a <strong><em>poor conductor of electricity<\/em><\/strong>, resulting in its applications in wiring and electrical components being limited.<\/p>\n<p>Lead is also a good thermal conductor. It has a thermal conductivity of 35.3 W\/mK, which enables it to efficiently transfer heat.
