The electron cloud geometry in turn determines the geometry in space of the bonded atoms called the "molecular geometry”. Note that the electron cloud geometry “ARRANGEMENT” is only theoretical, whereas the molecular geometry “SHAPE” and the associated bond angles are …

Molecular Geometry. According to Valence Shell Electron Pair Repulsion (VSEPR) Theory, the valence electron pairs that surround an atom repel each other due to their like negative charges. In order to minimize this repulsion, the electron pairs should be positioned around the atom so that they are as far apart as possible.

ELECTRONIC GEOMETRY—the basic arrangement of atoms about a central atom. It is determined by counting the total number of atoms bound to central atom and adding it to the number of lone pairs on the central atom. This total will be equal to a value 1-6. Those numbers correspond to one of the basis shapes in bold . MOLECULAR GEOMETRY

Molecular shape determines a compound’s state of matter, boiling point, freezing point, viscosity, volatility, surface tension and the nature of its reactions. *The geometry of a small molecule can be predicted by examining the central atom and identifying the number of atoms bonded to it and the number of unshared electron pairs surrounding it.

The trigonal pyramidal geometry molecular geometry of NH3 is a consequence of its tetrahedral electron-pair geometry. When describing the shapes of molecules, we always give the molecular geometry rather than the electron-pair geometry. The following are the steps used to predict molecular geometries with the VSEPR model:
