A tetrahedron is a triangular pyramid with 4 faces; each is a triangle. A regular tetrahedron has all edge lengths equal. There are formulas for the volume and surface area of a tetrahedron:
A few molecules have a tetrahedral geometry with no central atom. An inorganic example is tetraphosphorus (P 4) which has four phosphorus atoms at the vertices of a tetrahedron and each bonded to the other three.mmonia (NH 3) can be classified as tetrahedral, if one considers the lone pair as a ligand as in the language of VSEPR theory. The H-N-H angles are 107Â°, being contracted from 109.4Â°, a difference attributed to the influence of the lone pair.
