What is the texture of lead?
Lead is a bluish-gray, soft, dense metal that has a bright luster when freshly cut. It tarnishes slowly in moist air to form a dull gray coating. The metal is highly ductile and malleable.
What are the physical states of matter?
There are three common states of matter:
- Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other.
- Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded.
- Gases – no definite volume or shape.
Is lead formed from uranium?
Lead is formed both by neutron-absorption processes and the decay of radionuclides of heavier elements. Three stable lead nuclides are the end products of radioactive decay in the three natural decay series: uranium (decays to lead-206), thorium (decays to lead-208), and actinium (decays to lead-207).
Is lead a noble metal?
Key Takeaways: Noble Metal According to this definition, gold, silver, and copper are noble metals. Another definition of a noble metal is one which resists oxidation and corrosion. This excludes copper, but adds in other platinum group metals, such as rhodium, palladium, ruthenium, osmium, and iridium.
What are the chemical and physical properties of 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 made from lead?
The single most important commercial use of lead is in the manufacture of lead-acid storage batteries (see battery, electric). It is also used in alloys such as fusible metals, antifriction metals, solder, and type metal. Shot lead is an alloy of lead, antimony, and arsenic. Lead foil is made with lead alloys.

What is the atomic number of lead?
Lead is an element of the periodic table with an atomic number of 82. Lead (Pb) is a metal which has been used by humans for centuries dating back to 7000 BC. The element is present in various minerals in minute quantities excluding sulphide and lead glance (PBS) which is used to produce the metal around the world.
What is the chemical identity of lead?
CHEMICAL IDENTITY. Lead is a naturally occurring element and is a member of Group 14 (IVA) of the periodic table. 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%).
Which of the following is a characteristic of lead?
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.
