WebCovalent bonds meanwhile usually occur between non-metals. As long as the individual atoms can form an octet of electrons from sharing electrons in a covalent bond, there's always a possibility. So nitrogen for example is a non-metal with 5 valence electrons and needs 3 more for an octet, and can form a variety of covalent bonds. WebThe activated complex then can generate a covalent linkage between the ligand and the support, resulting in ligand immobilization. The type of linkage that is formed between the matrix and the immobilized ligand affects the performance of the affinity support in a number of ways. For example, if the linkage blocks or adversely affects the ...
