Thread: Structure of Such Atoms as Iron

Hey! So, as we were all tought in eighth grade, the configuration of electrons within an atom will be in layers, the first of which holding only up to two, after which eight. The only seven elements which have complete rings are called Noble Gasses. How is it that Iron, which has 26 electrons, is not a noble gas? ( Edit : Oh, sorry. I realize that the Periodic Table averages all the stable isotopes to get an Atomic Number[ Should that be capitalized? ]. I guess I knew that.. )
