A water molecule, because of its shape, is a polar molecule. That
is, it has one side that is positively charged and one side that is negatively charged.
The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the
atoms are called covalent bonds, because the atoms share electrons. The hydrogen atoms
have one electron each.
Because they share those electrons with the oxygen atom, the
electrons tend to stay close to the oxygen atom and the outside of the hydrogen atom tends
to be positively charged. The oxygen atom has eight electrons. Most of those tend to stay
away from the hydrogen atoms, and cause the outside of the oxygen atom to have a negative
When two water molecules get close together, the polar forces work
to draw the molecules together. The oxygen atom of one water molecule will bond with
several hydrogen atoms of other water molecules. These bonds are called hydrogen bonds.
Hydrogen bonds are not as strong as covalent bonds, but they are strong enough to bind
water molecules together and give water its unique characteristics. (An analogy concerning
the bonds is that the covalent bonds are like a strong glue bond while the hydrogen bonds
are like the bond between two toy magnets).
Two of those characteristics are: water's great ability to dissolve
materials, and water's lower density when it is frozen. At any time about 20% of the water
molecules in liquid water are freed of their hydrogen bonds and able to
"hydrate" other materials in the water.
The Triangular Wave treatment technology takes advantage of this
unique characteristic of water, a polar molecule.
