Iron comes from the Latin word ferrum. From ferrum its symbol became Fe. The atomic figure of Fe is 26, and its atomic weight is 55.845. Iron is a magnetic, pliable, glistening white metallic component.
Pure Fe has a hardness that ranges from 4 to 5. It is soft and malleable. Iron can be easy magnetized at ordinary temperatures and at 790°C the magnetic belongings disappears. Pure Fe thaws at about 1535°C, boils at 2750°C, and has a specific gravitation of 7.86. Chemically, Fe is an active metal. When exposed to humid air, Fe signifiers a red-brown, flakey, decay known as rust.
Iron is the 4th most abundant component in the Earth’s crust. Because it is so common, Fe has been used by human society for 1000s of old ages. Iron was known and used for arms in prehistoric ages, the earliest illustration still in being; a group of rusty Fe beads found in Egypt, dates from about 4000BC. This period in history was given the name Iron Age because it was the clip when people found ways to acquire Fe and to utilize it for edifice tools and arms.
The beginnings of modern processing of Fe can be traced back to cardinal Europe in the mid-14th century BC. Pure Fe has limited usage in today’s universe. Commercial Fe ever contains little sums of C and other drosss that change its physical belongingss, which are much improved by the farther add-on of C and other debasing elements. This helps to forestall oxidization, besides known as rust.
Iron is an indispensable portion of a healthy diet. Iron compounds are employed for medicative intents in the intervention of anaemia, when the sum of haemoglobin or the figure of ruddy blood atoms in the blood is lowered. Iron is a constituent of the complex compound in ruddy blood cells called haemoglobin. This substance is responsible for transporting O from your lungs to the remainder of your organic structure.
In decision, Fe is one of the most abundant and often used elements on Earth. It possesses many desirable traits which make it so utile in mundane life.
