When substances participate in chemical bonding and yield compounds, the stability of the resulting compound can be gauged by the type of chemical bonds it contains. The weaker forces will be discussed in a later concept. There are many types of chemical bonds that can form, however the 3 main types are. The strongest bonds that are present in biochemicals are covalent bonds, such as the bonds that hold the atoms together within the individual bases shown in figure 1. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. We will learn about the different kinds of bonds, ways chemists draw bonds and molecules, and how the type of chemical bonding affects the bulk properties of a material. Ionic bond electrostatic forces hold together oppositely charged ions. Take a closer look at the chemical bonds responsible for protein structure.
Basic concepts of chemical bonding lamar university. Chemical bonds form when electrons can be simultaneously close to two or more nuclei, but beyond this, there is no simple, easily understood theory that would not only explain why atoms bind together to form molecules, but would also predict the threedimensional structures of the resulting compounds as well as the energies and other properties of the bonds themselves. Proteins are biological polymers constructed from amino acids joined together to form peptides. A chemical bond is the physical process that causes atoms and molecules to be attracted to each other and held together in more stable chemical compounds.
