WebTerms in this set (43) Molecular geometry is specified for a central atom in a structure. A "central" atom is _____. any atom that is bonded to two or more other atoms. True or false: When using VSEPR theory to determine molecular shape, a triple bond counts as a single electron domain even though it consists of 3 shared electron pairs. True. WebShapes of Molecules. Step 4: Determine a stable arrangement of electron pairs around the central atom so that they experience the least repulsion. Step 5: Observe and find the lone pair-lone pair interaction, lone pair-bond pair interaction and bond pair-bond pair interaction. This is useful in determining the bond angles.
