About Iron
Now that the history of this interesting element has been clarified let us talk a little about the element iron itself. Let us start with the basic knowledge about it. In Mendelev's square the element iron has a 6 at the top of it and this is called the atomic number; for iron it happens to be 26. This means that one atom of the element iron has 26 positive charged particles in it's nucleus. Another important information for this element is it's atomic mass. An atom's atomic mass basicly consists of the mass of the protons and neutrons. These are then measured in AMU's, (atomic mass units). Even though a atom also has electrons, which are negatively charged particles orbiting its nucleus, the weight of the electrons is not important. This is because one proton equals aproximantelly 1,873 electrons. Knowing the meaning of the chemical symbol for Iron is also important, it's chemical symbol is Fe. The definition for the symbol Fe is an origin of the word ferrum. This was then adjusted to many languages such as portuguese and spanish. In portuguese iron is ferro and in spanish it is hierro. Iron is a strong but malleable metal. It is the most abundant metal by mass in the universe. It's production in our world is huge and it is in every room we walk in, it is essential for our lives, from humans to the smallest organisms. Iron is a metal and it is a solid at room temperature. Some of the properties of this element are that it is metallic, gray in color, it has no odor but it is lustrous, which means it reflects light easily. Below you can see a picture of Iron (Fe):
