Water Molecule Model Information Sheet Water is the most unusual molecule, with physical and chemical properties found in no other material. Its also the most abundant naturally occurring liquid, unlike most liquids,water can occur in a gas, liquid, and solid state. As we know, water is neutral, because the O atom is larger than H atoms this gives water a slight overall charge called polarity. Polarity really does allow bonding, they are hydrogen bonds which are very weak, so they don’t really last long, but continually break and reform. The most important property of a water molecule is that due to an even distribution of electrons, it is slightly charged on each end. This type of bonding occurs between two of the same element or elements close to each other in the periodic table. An hydrogen bond is the attractive force between the hydrogen attached to an electronegative atom of one molecule of a different molecule. A hydrogen bond is formed when a charged part of a molecule having polar covalent bonds forms an electrostatic( charge, as in positive attracted to negative) interaction with a substance of opposite charge. The forces due to polarity are cohesion and adhesion. The hydrogen bonds that hold the substances together is cohesion. It can also be visually seen as the water droplets formed. The attraction of a water molecule to another polar molecule is adhesion. For example if you take a cup of water and splashed it on a wall, the water molecules would not bounce off due to adhesion. Surface tension is a measure of how difficult it is to stretch or break the surface of liquid. In other words it behaves like a flexible sheet allowing objects thats denser than it to sit on the surface of water. Specific Heat is the amount of heat that must be absorbed or lost for 1g of that substance to change its temperature by 1 celsius.Heat of vaporization is
