Therefore, the original substance is an element. Ammonia has a hydrogen atom bonded to a nitrogen atom, which is electronegative enough to participate in hydrogen . Each bond corresponds to a pair of shared electrons (one from carbon and one from hydrogen), giving carbon the eight electrons it needs for a full outer shell. Covalent bonds are directional, meaning that atoms so bonded prefer specific orientations relative to one another; this in turn gives molecules definite shapes, as in the angular (bent) structure of the H2O molecule. The second has a Some covalent species form discrete molecules, known as simple covalent molecules, made up of just a few atoms joined with covalent bonds. A. O2. The simplest interpretation of the decrease in energy that occurs when electrons are shared is that both electrons lie between two attracting centres (the nuclei of the two atoms linked by the bond) and hence lie lower in energy than when they experience the attraction of a single centre.
