What has an atomic mass of 208?
Lead
Lead, isotope of mass 208.
Why is PB 208 the most stable?
Some consider lead to be the most stable element of all because of its high atomic number. Lead has three stable isotopes and one unstable isotope. All of them are natural. The stable isotopes Pb-206, 207 and 208 are generated from isotopes of the elements thorium and uranium.
Why is the atomic symbol for 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 208 a stable element?
Lead 208 Metal (Lead-208) is a stable (non-radioactive) isotope of Lead. It is both naturally occurring and a produced by fission. Lead 208 Metal is one of over 250 stable Metallic isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications.
What is the mass of 208 lead isotope?
Lead-208 Lead, isotope of mass 208 13966-28-4 3 Chemical and Physical Properties
What is the mass of an atom of lead?
Atomic Mass of Lead. Atomic mass of Lead is 207.2 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
What is the composition of 208 Pb?
While it only makes up approximately half of the composition of lead in most places on Earth, it can be found naturally enriched up to around 90% in thorium ores. 208 Pb is the heaviest known stable isotope of any element, and also the heaviest known doubly magic nucleus, as Z = 82 and N = 126 correspond to closed nuclear shells.
