How do you write a lead in chemistry?
Lead (Pb), a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table.
What is chemical name of Pb?
Atomic Names and Symbols
What is the formula of lead?
Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82.
What is lead used in today?
Lead and lead compounds have been used in a wide variety of products found in and around our homes, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition and cosmetics.
What is lead made up of?
Lead (element #82, symbol Pb) is a very soft, blue-gray, metallic element. It is primarily produced from the mineral galena. It has been used since antiquity.
What are 5 Chemical Properties lead?
Its properties include a low melting point; ease of casting; high density; low strength; ease of fabrication; acid resistance; electrochemical reaction with sulfuric acid; chemical stability in air, water, and soils; and the ability to attenuate sound waves, atomic radiation, and mechanical vibration (11).
What is full name Pb?
Lead is a chemical element with symbol Pb and atomic number 82. Classified as a post-transition metal, Lead is a solid at room temperature.
What is the chemical name of H?
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element.
Where is lead found naturally?
Lead can be found in all parts of our environment – the air, the soil, the water, and even inside our homes. Much of our exposure comes from human activities including the use of fossil fuels including past use of leaded gasoline, some types of industrial facilities and past use of lead-based paint in homes.
What is the name of Li2S?
Lithium sulfide (Li2S)
Where is lead used?
Lead and lead compounds have been used in a wide variety of products found in and around our homes, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition and cosmetics. Lead may enter the environment from these past and current uses.
Which is the best description of the properties of lead?
Pure lead has a bright, silvery appearance with a hint of blue. It tarnishes on contact with moist air and takes on a dull appearance, the hue of which depends on the prevailing conditions. Characteristic properties of lead include high density, malleability, ductility, and high resistance to corrosion due to passivation.
What kind of structure does lead have on its face?
Lead consequently has a face-centered cubic structure like the similarly sized divalent metals calcium and strontium. Pure lead has a bright, silvery appearance with a hint of blue.
What are some of the symptoms of lead poisoning?
Symptoms of lead poisoning include nephropathy, colic-like abdominal pains, and possibly weakness in the fingers, wrists, or ankles. Small blood pressure increases, particularly in middle-aged and older people, may be apparent and can cause anemia.
How is the density of lead compared to other metals?
Lead’s close-packed face-centered cubic structure and high atomic weight result in a density of 11.34 g/cm 3, which is greater than that of common metals such as iron (7.87 g/cm 3), copper (8.93 g/cm 3), and zinc (7.14 g/cm 3). This density is the origin of the idiom to go over like a lead balloon.
