The creation of mathematical models of molecular properties and behaviors, their graphic descriptions are molecular graphics, but these topics are closely related, and each topic uses the techniques of other topics. In this article, "molecular model" will mainly refer to a system containing more than one atom and ignoring the nuclear structure. Electronic structures are also often omitted or represented in a highly complex manner. Learn more details from this diagram, or try to make yours with ease now.
