# Polarity of molecule

Chemistry Level 1

In chemistry, a space-filling model, also known as a calotte model, is a type of three-dimensional molecular model where the atoms are represented by spheres whose radii are proportional to the radii of the atoms and whose center-to-center distances are proportional to the distances between the atomic nuclei, all in the same scale. The above are space-filling models of four molecules. In a liquid state, which of these four substances will be attracted by an electrified body?
