Why is the element lead important?
Lead's high density makes it useful as a shield against X-ray and gamma-ray radiation and is used in X-ray machines and nuclear reactors. Lead is also used as a covering on some wires and cables to protect them from corrosion, as a material to absorb vibrations and sounds and in the manufacture of ammunition.
How is lead used in the world?
Overview. Lead is a naturally occurring toxic metal found in the Earth's crust. ... Lead is, however, also used in many other products, for example pigments, paints, solder, stained glass, lead crystal glassware, ammunition, ceramic glazes, jewellery, toys and some cosmetics and traditional medicines.
What is so special about lead?
Lead (Pb) is one of the most infamous elements in the periodic table. Though it's now widely known as the source of lead poisoning, humans have been using the heavy metal for thousands of years. It's soft, has a relatively low melting point, is easy to shape, and doesn't corrode much, making it incredibly useful.
What is elemental lead?
Lead is a chemical element with the 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.
Where does lead come from on Earth?
Lead is found in nature, rarely in pure form but in ores with other metals — the most abundant one in the Earth's crust being galena (PbS). Natural formation of lead occurs by radioactive decay of uranium and thorium through radon (222Rn).
How does lead impact the environment?
Other sources of lead to ecosystems include direct discharge of waste streams to water bodies and mining. Elevated lead in the environment can result in decreased growth and reproduction in plants and animals, and neurological effects in vertebrates.
What happens when lead enters the environment?
Lead can remain in the environment as dust indefinitely. The lead in fuels contribute to air pollution, especially in urban areas. Soils near highways, freeways, and smelting facilities have higher levels of lead than soils in other areas because of their exposure to lead dust, which accumulates over time.
What elements does lead react with?
Lead reacts vigorously with fluorine, F2, at room temperature, and chlorine, Cl2, when heated, forming the corresponding lead(II) halides [8].
What are lead atoms?
Lead is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is Pb, and its atomic number is 82, which means that a lead atom has 82 protons in its nucleus. Lead has the highest atomic number of any stable (non-radioactive) element.
Why is lead so heavy?
Lead is a stable metal that's often used as weights and sinkers. The reason it's heavy in terms of mass per unit volume (or think about it as per teaspoon), is because the lead atoms are very close, making it a dense material.
Is lead valuable?
Why Is Lead Valuable? Lead is a soft, dense metal with a low melting point. It is an important component in battery production. Furthermore, lead's high density and resistance to corrosion make it useful in industries ranging from piping to X-rays.
What is made of lead?
It is used in ammunition (shot and bullets) and as a constituent of solder, type metal, bearing alloys, fusible alloys, and pewter. In heavy and industrial machinery, sheets and other parts made from lead compounds may be used to dampen noise and vibration.
Why is lead so toxic?
Lead is bad for humans because it interferes with numerous enzymes inside the cells of these organs. This results in symptoms such as muscle and joint aches as well as constipation and overall fatigue. It damages our brains by interfering with how brain cells send messages and communicate.
How does lead get into the drinking water?
Lead can enter drinking water when plumbing materials that contain lead corrode, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. The most common sources of lead in drinking water are lead pipes, faucets, and fixtures.
