Carbon is element number 14 on the periodic table. It has a molecular weight of 12 g/mol. Each carbon atom has four electrons available to form covalent bonds. Diamond and graphite are two of the most common natural forms of carbon that exist. These structures differ in their physical forms...
When atoms of two different elements catenate in alternation, the chain gains strength from the disparity in electronegativity between them, such as siloxane—it has a large electronegativity difference. This chapter discusses the homocatenation of carbon and sulfur. Carbon, having a normal valence of...

This means that two of the eighteen electrons of the ethane molecule must be so firmly occupied by forming a single carbon-carbon σ-bond that both carbon atoms, obviously being equivalent, still can be considered in some sense to be carbon (IV) like in methane. This situation cannot be ...
