Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it throughout your body. Hemoglobin represents about two-thirds of the body's iron. If you don't have enough iron, your body can't make enough healthy oxygen-carrying red blood cells...

Iron is the most used metal in our lives. Iron is indeed an incredibly useful substance and we use itabundantly because it extremely strong than copper or wood and less brittle when compared tostrong. Iron can also be easily shaped into various form if it is heated properly, allowing us to maketools as our needs and unlike the wood, it can handle very high temperature.
The unique property of iron is that you can magnetize it and make useful in the making of electricmotors and generators. The most interesting thing is that we will not have to worried about theshortage of this material because it occupy 5 percent of the earth's crust and some ores containsabout !" percent of iron. In addition, those ores can easily be extracted from earth.
Let's compare iron with another element, aluminum.refining aluminum needs huge amountelectricity and to shape it, you have to either extrude it or cast it. Iron is, however, much easier to useand also harder than aluminum. The substance has been very useful to people for a long time, whilealuminum is not effective as iron and it is not abundant on earth.
The only real problem about Iron is rust which is controllable. one can easily control it bygalvanizing, chrome plating or painting. To control it, you must be sure that iron is not in contact ofair because air moisture is the reason why rust forms on the iron.
The day will come when we will be very advanced in terms of technology and iron will be completelyreplaced by plastics, aluminum, things like glass fibers and carbon, but it is not these days. Thesedays we use iron because economic equations tell us that iron inexpensive iron has manyadvantages over those expensive alternatives.
Iron is a metal which is the most common element found in the earth and the sixth most commonelement in the universe. It forms much of the outer and inner core of the earth and is also found inthe rocky planets. This metallic element has an atomic number of &' and the group and periodnumber in the periodic table are (III and ) respectively.
atomic structure: atomic number is 26', which means it has &' electrons and the outer orbital holds &free electrons that form ionic bonds with the non-metal elements. In the nuclease, it has 26' protonsand 30" neutrons.
