The properties of a carbon fiber part are close Carbon is unique in that it has 6 protons and 6 electrons. Carbon has 4 valence electrons, and can form long chains with itself. In addition to sharing electrons with metals and non-metals of moderate electronegativity, carbon can also donate or accept electrons, giving rise to organic salts. Iron porphyrin, which is the oxygen binding site of hemoglobin, is such an example. Carbon plays a particularly important role in these molecules by virtue of its unique chemical properties. At this stage, it can return to its original shape when the stress is removed. These allotropes include graphite and diamond, which have very different properties. Silicon is another element that can bond with itself and form long chains, but the large size of silicon atoms makes it incapable of forming as large a variety of compounds as carbon. Through a process of heat treating, ultra-high-carbon steel (1.25-2 percent carbon) can be tempered to great hardness and used for the manufacture of knifes. Carbon is small and has four valence electrons; these factors combine into a unique structure that allows it to easily make a chain of carbon atoms. In a graphene layer, each carbon atom is bonded covalently to three other atoms, leaving the fourth electron free to migrate in the plane, hence its electrical conductivity. Carbon-14 has very low natural abundance (0.0000000001 percent), but its long half-life makes it useful for radiometric dating. When it reaches a point (upper yield point) where it can no longer return to its original dimensions, it undergoes plastic deformation, which is a permanent and irreversible.
