Lead is a heavy, soft, gray solid. It is both ductile and malleable. Ductile means capable of being drawn into thin wires. Malleable means capable of being hammered into thin sheets. It has a shiny surface when first cut, but it slowly tarnishes (rusts) and becomes dull. Lead is easily worked.
Lead is a soft, highly malleable and bluish-white lustrous metal with atomic no. 82. Understand the uses of lead, lead melting point, the density of lead and atomic mass.
22 Νοε 2024 · 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.
Lead is a neurotoxin that accumulates in soft tissues and bones. It damages the nervous system and interferes with the function of biological enzymes, causing neurological disorders ranging from behavioral problems to brain damage, and also affects general health, cardiovascular, and renal systems.
27 Ιουν 2024 · Lead(II) Sulfide (PbS) Description: A black, insoluble solid that occurs naturally as the mineral galena. Chemical Equation: Pb+S→PbS (Direct combination of lead and sulfur) Uses: PbS is used in semiconductors, infrared detectors, and in the vulcanization of rubber. Lead(II) Chloride (PbCl₂)
The atomic number of lead, which is 82, indicates that it has 82 protons in its nucleus. This high number of protons, along with the corresponding number of electrons, gives lead its heavy, dense, and relatively stable nature. Additionally, the atomic mass of lead, which is approximately 207.2 g/mol, is one of the highest among the stable elements.
