8th grade chemistry: IV. molar mass: Empirical formula

4. 3D Structural formula: Molecules are three dimensional (3D) objects. The 3D structural formula is an attempt to convey the 3D geometry of the molecule. dashed bonds depict atoms going in back of the plane. Note: The triangular bonds depict atoms coming out of the plane and the dashed bonds depict atoms going in back of the plane. Go Here if you would like to learn more about 3D structures
