摘要

In introductory chemistry courses the concept of the chemical bond is of major importance.Various types of chemical bonds such as ionic,covalent,and coordinate co-valent are presented and explained,and shown in what systems and compounds they are found.It is pointed out that numerous chemical compounds are actually coordination complexes.Many of them,based on rather complicated ligands,are important in major life processes.
