Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE. Pure iron is a silvery-white metal that's easy to work and shape and it's just soft enough to cut through (with quite a bit of difficulty) using a knife. Nitroglycerin is very dangerous because it explodes easily; neon poses almost no hazard because it is very unreactive. Iron is chemically active and forms two major series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III), or ferric, compounds. Adding another proton would create the atom of the element cobalt. Alloy steel also has carbon, but the iron is also alloyed with other elements. Iron melts from the surface at about 1750 ° F (1510 degrees C). History .

Iron is a metal, an element of group VIII of the periodic table. Iron has an important biological application, as the prime constituent of the oxygen carrying molecule called Hemoglobin. The melting point of iron ( Fe) at the outer (liquid) core-inner (solid) core (330 GPa) pressures at a depth of 5150 km in the Earth was suggested to provide an absolute temperature limit. In four distinct crystalline shapes, it is recognised to occur. Iron is the most abundant metal on Earth and is believed to be the tenth most abundant element in the universe. These three allotropic forms of Iron are known as delta, gamma and alpha Iron. The boiling point of iron is 2861 °C. Steel is just the iron component refined to regulate the carbon quantity. Iron does not possess a singular form of crystalline structure, but shows three different forms or ‘allotropes’. Iron makes up 5% of the Earth's crust and is one of the most abundantly available metals. I plain iron, (ii) wrought iron, (iii) cast iron, (iv) pig iron, and (v) direct reduced iron are classified as such materials. Iron has twenty-six protons, so its atomic number is 26.
