WebA water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other. WebCreated by LABScI at Stanford 1 Surface Tension: Liquids Stick Together Teacher Advanced Version In this lab you will learn about properties of liquids, specifically cohesion, adhesion, and surface tension. These principles will be demonstrated by adding drops of different liquids onto pennies to determine the strength of molecular attraction.
