Is lead a chemical or physical property?
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.
What are characteristics of lead?
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, as is indicated by the continuing use of lead water pipes installed by the ancient Romans.

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 are the chemicals in lead?
Natural lead is a mixture of four stable isotopes, 208Pb (51–53%), 206Pb (23.5– −27%), 207Pb (20.5–23%), and 204Pb (1.35–1.5%). Lead isotopes are the stable decay product of three naturally radioactive elements: 206Pb from uranium, 207Pb from actinium, and 208Pb from thorium.
What are some interesting facts about lead?
Here are some of the interesting facts about lead. First of all, lead is defined as a soft, malleable, dense and ductile metallic element. Its original color is bluish white and is commonly extracted from galena and is mostly found in ore along with other elements such as zinc, copper and silver.
What are the important uses of lead?
Uses of lead One of the most common uses of lead is in the automobile industry. Another common used of lead is in bullets and shot. Lead is used as solder for electronics, but for safety reasons attempts are being made to replace lead solder with bismuth. It is commonly used in construction for roofing materials.
Where can lead be found naturally?
Lead is a naturally occurring metal found in the earth’s crust. Lead can be found many places, much because of human activity through burning fossil fuels, mining, and manufacturing. Water can be contaminated with lead from mines, waste dumps, and industrial plants.
What are the special properties of lead?
Properties of Lead Lead (Pb) is a white lustrous metal with a soft texture and is highly malleable. The metal is highly corrosion resistant, in addition to not being a poor conductor of electricity. The metal in its powdered form produces a bluish-white flame when burnt in air. Once mixed with fluorine in room temperature forms lead fluoride.
