About Water and Water Clusters
Water is an amazing and unique molecule. Our bodies and all living creatures on Earth depend upon this remarkable molecule for life. While water is said to have many magical qualities, science has studied it intensely. Today, lots of information and data has been collected regarding water making it perhaps the most well known substance on earth.
Water is made up of 2 hydrogen atoms and one oxygen atom. In its chemical form it is written as H2O. It should be noted that both atoms of hydrogen form a covalent bond to the oxygen. A covalent bond is a term used when chemicals share pairs of electrons (which is a part of an atom) amongst other atoms. In water's case, 2 hydrogen atoms share electrons with the Oxygen atom creating a bond. Many of water's properties are a result of its covalent bonds and the structure of this molecule once it bonds.
For instance, water is a neutral molecule, as opposed to positive or negatively charged. However, due to the structure of the water molecule, the positive and negative charges that balance out its neutrality are not distributed uniformly the result of this charge displacement is that the water molecule creates an electric dipole.
You probably already learned that opposite charges attract, so the partially positive hydrogen atom on one water molecule is electro-statically attracted to the partially negative oxygen atom on a neighboring molecule. This process is called hydrogen bonding. In a water molecule the hydrogen bond is considerably weaker. It is so weak that any hydrogen bond between water molecules cannot survive for more than a tiny fraction of a second. This is important to note, because it is one of the main reasons water forms in clusters.
A Few Facts About Water
H20 molecules attract each other through dipole to dipole interactions known as hydrogen bonding.
H2O molecules that are in hydrogen-bonded clusters are the molecularly favorable configuration.
A hydrogen-bonded cluster of water is four H2O molecules that are located at the corners of an imaginary tetrahedron.
H2O hydrogen-bonded clusters undergo rapid thermal motions on a time scale of picoseconds. This means that the lifetime of any specific water cluster will be extremely brief.
A lot of scientific interest has been directed at clusters of water. While many studies have been done and water clusters have been frequently observed using the latest technologies, there are still many questions that are left unanswered. Questions such as how does one distinguish molecules that are part of a cluster, from those molecules adjacent to it that are not? Another important question to ask is whether water clusters have any meaningful existence due to the fact they form for fleeting periods of time.
With lots of research being done, more light is being shed on the structure and properties of water clusters. Since they form new bonds many times per second, it can be difficult to isolate water clusters- even in the lab. However, new research suggests that the answers may be close at hand. Recently, an important discovery stated that 80% percent of water molecules that are bound are done so in chain-like fashion- only bonding to two other molecules at a time at room temperature. This finding has reinforced the view of a dynamically changing disordered water structure called the water cluster.
