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.

Where can the chemical lead be found?
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 are 3 interesting facts about lead?
Interesting Lead Element Facts
- Lead has atomic number 82, which means each lead atom has 82 protons.
- Lead is a considered a basic metal or post-transition metal.
- Lead is one of the metals that was known to ancient man.
- Over half the lead produced today is used in lead-acid car batteries.
- Lead is highly toxic.
What is lead mainly used for?
Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection and in some solders. It is often used to store corrosive liquids.
Why is lead so abundant?
The third reason is that the abundance of lead is continually increased from the other direction by the radioactive decay of heavier elements. Most radioactive elements, including the relatively abundant U and Th have decay routes that lead them to stable lead nuclei.
Where is lead found in homes?
Products. Lead has been used for a long time in a wide variety of products found in and around our homes, including painted toys, furniture and toy jewelry; cosmetics; food or liquid containers; and plumbing materials.
How does lead get into rivers?
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.
Why was lead so commonly used?
Lead used to be called the “useful metal” that could be added to many products, including paint. He says it was because lead is easy to melt — a campfire alone can do it. Unlike iron, lead is malleable.
What color is lead?
When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is a relatively unreactive post-transition metal.
Who was lead discovered by?
Lead was one of the earliest metals discovered by the human race and was in use by 3000 B.C. The ancient Romans used lead for making water pipes and lining baths, and the plumber who joins and mends pipes takes his name from the Latin word plumbum, meaning lead.
How is lead used in industry?
Lead is widely used in batteries, cable sheaths, machinery manufacturing, shipbuilding, light industry, lead oxide, radiation protection and other industries.
What lead looks like?
Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air.
How is lead obtained?
Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts. Lead is a soft, malleable and corrosion resistant material. Lead is used to line tanks that store corrosive liquids, such as sulfuric acid (H2SO4).
How is lead formed in stars?
Stars a few times bigger than our sun explode when they run out of energy at the end of their lifetimes. The energies released in this fleeting moment dwarf that of the star’s entire lifetime. These explosions have the energy to create elements heavier than iron, including uranium, lead and platinum.
Is there more lead than gold?
Gold is much heavier than lead. It is very dense. Therefore gold weighs 19.3 times as much or (19.3 x 8.3 lb) about 160 pounds per gallon. Although gold has a density 19.3 times greater than water and is one of the most dense substances on Earth, there are substances with far more amazing densities.
Is lead heavier than steel?
Steel is less dense than lead. The pellets weigh one-third less than lead pellets of the same size. Steel retains less energy and may not kill birds cleanly at the same ranges.
