- Symmetry axis: an axis around which a rotation by 360 ∘ n {displaystyle {tfrac {360^ {circ }} {n}}} results in a molecule indistinguishable from the original. This is also called an n -fold rotational axis and abbreviated Cn. Examples are the C2 axis in water and the C3 axis in ammonia.

May 31, 2016 · The symmetry element consists of all the points that stay in the same place when the symmetry operation is performed. In a rotation, the line of points that stay in the same place constitute a symmetry axis; in a reflection the points that remain unchanged make up a plane of symmetry.

- 3.2: Symmetry Operations and Elements
An example of a symmetry operation is a 180° rotation of a water molecule in which the resulting position of the molecule is indistinguishable from the original position (see Figure 3.2.1 3.2. 1). In this example, the symmetry operation is the rotation and the symmetry element is the axis of rotation.

The word symmetry implies balance. Symmetry can be applied to various contexts and situations.
This comprehensive guide will provide you with a seamless understanding of symmetry elements starting with its basic meaning, historical evolution, examples found in everyday life and intricate chemical structures like benzene.
A symmetry operation is an action that leaves an object looking the same after it has been carried out. For example, if we take a molecule of water and rotate it by 180° about an axis passing through the central O atom (between the two H atoms) it will look the same as before.
A symmetry element can be a point, axis, or plane. A symmetry operation is the movement of a body (molecule) such that after the movement the molecule appears the same as before.
