Some common shapes of simple molecules include: • Linear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180°. For example, carbon dioxide and nitric oxide have a linear molecular shape. • Trigonal planar: Molecules with the trigonal planar shape are somewhat triangular and in one plane (flat). Conseq… WebbThe Shape of Molecules. The three dimensional shape or configuration of a molecule is an important characteristic. This shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners. Three dimensional configurations are best viewed with the aid of models. dave chang noodles
