SEP Develop a Model The element argon (Ar) has eight valence electrons
and is a liquid at very low temperatures. Sketch a model of two argon
atoms and where each atom's electrons need to be in order for an attractive
dispersion force to occur. Make a similar sketch that explains why larger
molecules typically experience larger dispersion forces.
