will happen when these two water molecules approach each other?
the Water Dimer Page for a Flash Animation.
What did you observe?
What are some properties of a single water molecule?
represents a different atom type. What type of atom is red? white?
following images show a single water molecule after it has been rotated 90, 180,
270 and 360 degrees.
water show any symmetry?
is formed when two atoms of hydrogen combine with one atom of oxygen. The single
electrons in the hydrogen atoms are drawn to oxygen which only has 6 electrons
in its valence shell. How will this affect the charge on the water molecule?
physics you learned that like charges repel and unlike charges attract. The above
animation shows what happens when two water molecules approach. What would expect
might happen if we surround a single molecule of water with four other molecules
of water? Take a look at this image frozen in time.
on image for pattern
you recognize any familiar geometric pattern? What distances might each water
molecule be from each other?
you predict the pattern for 8 water molecules?
above simulations were all performed at very low temperatures (below the freezing
point of water. At higher temperatures molecules are in rapid motion. What would
you expect the motion to look like at a higher temperature, say at room temperature?
