What Is Molecule Structure
This section provides a quick introduction on what is atomic bond that ties atoms together to form molecules.
What Is Molecule Structure? - Molecule Structure is a graphical model of a molecule on how its atoms are bonded together, with information about atom types/sizes/locations and bound types.
Molecule Structures are 3-dimensional structures which can be visualized in different models. Two examples are list below:
Skeletal Formula - Also called line-angle formula or shorthand formula. Skeletal Formula uses line segments to represent atomic bonds, intersections/ends of line segments to represent atoms, and element symbols to identify atom types. For example, the picture below shows a Skeletal Formula of the Methane molecule:
Ball-and-Stick Model - Ball-and-Stick Model uses balls to represent atoms, sticks to represent bonds, and colors to identify atom types. For example, the picture below shows a Ball-and-Stick Model of the Methane molecule:
