What is the chemical formula of Pb?
Lead Metal is an element with atomic symbol Pb, atomic number 82, and atomic weight 207.2. Lead(0) is an elemental lead.
Why is the element lead Pb?
The chemical symbol for lead is Pb, which comes from the Latin word plumbum, meaning “waterworks,” referring back to ancient times when the metal was widely used in the construction of water pipes. Although there are 27 lead isotopes, only four are considered stable.
Is lead a mineral?
Lead is a soft, malleable, ductile and dense metallic element. It is extracted chiefly from the mineral galena and found in ore that also contains zinc, silver and copper.
Is lead a compound?
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.
What is the atomic number of PB?
82
Is lead a atom?
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.
Is PB transition metal?
The elements which follow lanthanum (Z=57) and actinium (Z=89) are called the lanthanides and actinides, respectively, and together are known as the inner transition elements.The Transition Metals. Pt Au Hg 3A Tl 4A Pb.

Why is lead called lead?
In the 16th century, a large deposit of pure, solid graphite was discovered in Borrowdale, England. Thus, they called it “plumbago”, which is derived from “plumbum”, which is Latin for “lead”. It didn’t take people long to realize that solid sticks of high quality graphite were good for marking things.

Is lead a rock?
The ancient Egyptians also used lead in the glazes on their pottery. Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.PROPERTIES OF LEAD. Atomic Symbol Pb Atomic Number 82.
What is lead made by?
It is primarily produced from the mineral galena. It has been used since antiquity. Water pipes in ancient Rome, some of which still carry water, were made of lead. The English words plumber and plumbing are derived from the Latin word for lead — plumbum — the source of the chemical symbol for lead, Pb.
Is tin a mineral?
Tin was one of the earliest-known metals. The dominant mineral of commercial importance as a source of tin is cassiterite; small quantities of tin are recovered from the complex sulfides, such as stannite and canfieldite.
