Iron is the most common element (by mass) on Earth, forming much of the outer and inner core, as well as the fourth most common element in the Earth's crust.
The Earth has enough Iron to make three new planets, each with the same mass as Mars.
It is the most widely-used metal because it is very strong and cheap. Iron is used to make bridges, buildings, nails, screws, pipes, girders, and towers.
Archaeologists have found several iron tools, weapons and cultural objects dating thousands of years before the advent of the Iron Age. These objects were held in high regard for their qualities and were made from meteoric iron - the only naturally occurring native metal of the element iron on the Earth's surface.
Genesis 4 v 22 contains the first mention of iron in the Old Testament of the Bible; "Tubal-cain, an instructor of every artificer in brass and iron."
Cast iron is an alloy of iron. As early as 1848 cast iron was used for a building constructed in New York City. By about 1855 architects had developed a type of construction that used a skeleton of metal--cast iron. Cast iron made possible floor spans of greater width than ever before.
Iron is plentiful because it is the final element formed out of a star's death.
Iron increases in weight as it rusts.
Iron is present in meat and is also found in hemoglobin in red blood cells.
Iron is the most common nutrient deficiency in the world.
The human body has enough iron to make a 3-inch long nail.
Some breakfast cereals, like Wheaties, are fortified with enough iron that individual flakes can be lifted and carried using common magnets.
Iron is toxic when large amounts are swallowed and can damage the body. When too many vitamins that have iron in them are consumed, people get sick.
