Select all the statements that correctly describe the five basic electron-domain geometries.

-An octahedral geometry indicates that there are six electron domains. -A system with three electron domains will have a trigonal planar electron-domain arrangement.

Match each ideal bond angle with the correct electron-domain geometry in each case.

90- octahedral 120- trigonal planar 109.5- tetrahedral 180- linear 90 and 120- trigonal bipyramidal

The electron-domain geometry of a species is the arrangement of electron _____ around the central atom, whereas the molecular geometry is the arrangement of bonded _____ . Two species with the same electron-domain geometry may have different molecular geometries.

domains; atoms

Molecular shape is determined by the number of electron domains around a central atom, where an electron domain may be a(n) _____ electron pair or any _____ between two atoms.

lone; bond
