Metallic iron is virtually unknown on the Earth's surface except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Although iron is the fourth-most abundant element in the Earth's crust, composing about 5%, the vast majority is bound in silicate or, more rarely, carbonate minerals, and smelting pure iron from these minerals would require a prohibitive amount of ...
This is a list of prices of chemical elements.Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.
Precious metals are rare, naturally occurring metallic chemical elements of high economic value. Precious metals, particularly the noble metals, are more corrosion resistant and less chemically reactive than most elements. They are usually ductile and have a high lustre.

Iron is a chemical element; it has the symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core.
From the outset, correcting an iron deficiency may seem small, but it can make a world of a difference in helping you feel empowered and in control of your health. Restoring iron to your body can ...
Ancient Greek mythic-cultural cosmology depicted a decline from a golden age to a silver age followed by an Iron Age.

In Japan, the traditional Sho Chiku Bai (松竹梅) ranking system has a hierarchy of pine 松 (matsu), bamboo 竹 (take), and plum 梅 (ume ...
