Spatial relationship of every atom in a molecule is known as:

The terms configuration and conformation are often confused: Configuration refers to the geometric relationship between a given set of atoms, for example, those that distinguish l- from d-amino acids. Interconversion of configurational alternatives requires breaking (and reforming) covalent bonds. Conformation refers to the spatial relationship of every atom in a molecule.
