構造式 化学式
A graphical representation of the [[chemistry|chemical]] compound's spatial arrangement of its atoms, molecular shape and often their chemical bonds. It comes in various models and can be either 2D or 3D. Unlike [[chemical formula]] which is limited to text.

For example, the chemical structure for water (H₂O) is a basic grid of one hydrogen molecule, one oxygen, and then another hydrogen. More complex substances thus require more complicated grids to outline every molecule present.
