Molecules Symmetry Elements and Operations

The three-dimensional symmetry of a molecule can be described by elements and operations  

1 A symmetry element is the point of reference (a point in space, a plane, or an axis, for example) around which the symmetry occurs. 

A symmetry operation is the rearrangement of atoms around a symmetry element. 

A molecule can possess five symmetry elements, about which symmetry operations can be performed  

In this section, I walk you through each of them.
