Tin is generated via the long s-process in low-to-medium mass stars (with masses of 0.6 to 10 times that of the Sun), and finally by beta decay of the heavy isotopes of indium. [51] Tin is the 49th most abundant element in Earth's crust, representing 2 ppm compared with 75 ppm for zinc, 50 ppm for copper, and 14 ppm for lead. [52]
Tin is an essential metal in the creation of tin- bronzes, and its acquisition was an important part of ancient cultures from the Bronze Age onward. Its use began in the Middle East and the Balkans around 3000 BC. Tin is a relatively rare element in the Earth's crust, with about two parts per million (ppm), compared to iron with 50,000 ppm ...
Perey discovered it as a decay product of 227 Ac. [172] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well.

Metals of antiquity. German amulet to protect against disease (18th century); it is made from an alloy of the seven alchemical metals: lead, tin, iron, gold, copper, mercury and silver. The metals of antiquity are the seven metals which humans had identified and found use for in prehistoric times in Africa, Europe and throughout Asia: [1] gold ...
James Smith (miner) James (Philosopher) Smith (1 July 1827 – 15 June 1897) [1] was a politician, goldminer, explorer and discoverer of tin reserves in Tasmania, Australia including the Mount Bischoff mine. Smith was born at Georgetown, Van Diemen's Land (now Tasmania), second of three children of John Smith and his wife Ann, née Grant. [1]
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows (" periods ") and columns (" groups "). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order ...
Scientists discovered a method to create element 116 using a titanium beam, paving the way for future synthesis of element 120, the "holy grail" of chemistry.
