When a molecule or polyatomic ion has only one central atom, the molecular structure completely describes the shape of the molecule. Larger molecules do not have a single central atom, but are connected by a chain of interior atoms that each possess a “local” geometry.
Explore molecule shapes by building molecules in 3D! How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare the model to real molecules!
Molecular geometry, also known as the molecular structure, is the three-dimensional structure or arrangement of atoms in a molecule. Understanding the molecular structure of a compound can help determine the polarity, reactivity, phase of matter, color, magnetism, as well as the biological activity.
A molecule consists of a central atom chemically bonded to several side atoms, resulting in a well-defined shape and a finite bond angle [1-4]. Molecular geometry is vital in chemistry to determine a substance’s physical and chemical properties, like color, reactivity, polarity, and state of matter.
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom.

Molecular shapes, or geometries, are critical to molecular recognition and function. Table \(\PageIndex{1}\) shows some examples of geometries where a central atom \(A\) is bonded to two or more \(X\) atoms.
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It gives information about the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom.
Explore molecule shapes by building molecules in 3D and see how different bonds and electron pairs affect the shape.
Molecular geometry or molecular structure is the three-dimensional arrangement of atoms within a molecule. It is important to be able to predict and understand the molecular structure of a molecule because many of the properties of a substance are determined by its geometry.
