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 soft?

How about hardness? The critical feature here is the shear modulus of the metal. … This is why metals with high melting temperatures (such as W and Ti) tend to be hard, while metals with low melting temperatures (such as lead and zinc) are soft.

What will dissolve lead?

Lead metal resists sulfuric and phosphoric acid but not hydrochloric or nitric acid; the outcome depends on insolubility and subsequent passivation of the product salt. Organic acids, such as acetic acid, dissolve lead in the presence of oxygen. Concentrated alkalis will dissolve lead and form plumbites.

What disease causes lead?

Because these symptoms may occur slowly or may be caused by other things, lead poisoning can be easily overlooked. Exposure to high levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death.

Where does lead come from naturally?

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).

How common is lead in nature?

Although lead makes up only about 0.0013% of the earth’s crust, it is not considered to be a rare element since it is easily mined and refined. 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.

How was lead discovered?

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.

What are 3 interesting facts about lead?

Interesting Lead Element FactsLead 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.More items…•

Why is lead so cheap?

The main reasons are the fact that lead is cheap, it’s abundantly available throughout the Earth, it has a pathetically low melting point, it isn’t good for a lot of things except as a weight in most cases – and bullets love mass to them – it grants them more “stopping power”…

Is Lead durable?

Lead (Pb), a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. … 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.

How heavy is lead?

Different materials have different densities. For example, the mass density of gold is 19.3 g/cc, lead is 11.4 g/cc, copper is 9.0 g/cc, aluminum is 2.7 g/cc, water is 1.0 g/cc (1g/cc = 1 gram per cubic centimeter). If we want the density in English units we could use 11.1 oz/cubic inch as the density of gold.

Is lead natural or man made?

Lead is a naturally occurring element found in small amounts in the earth’s crust. While it has some beneficial uses, it can be toxic to humans and animals, causing health effects.
