the molecular level symmetric patterns constantly show up.Even
a single water molecule shows symmetry.
1, which will appear on screen when lesson 4 is clicked
on, shows a single water molecule.
types of atoms is water composed of?____
**What is the chemical formula?_________
on the ends to demonstrate the location of the hydrogens.
The middle will show the oxygen.
the distances from oxygen to either hydrogen. What value
do you get?____________
the distance from either hydrogen to the oxygen the same?__
**What type of symmetry does this represent?_______
important to note that the units for the distance measurements
are all in "Angstroms". An Angstrom is 1/10,000,000,000
of a meter. Angstroms are always used when we measuring
at the atomic level. Can you give a reason why?
the angle represented for the water molecule on the screen.
Is it acute or obtuse?_____ What is the measure?_______
off the water molecule, and click on the methane molecule.
A methane molecule will appear. We have seen this shape
geometric shape do you think the methane will fit into?___________
on the tetrahedron box at the right side to demonstrate
this. Leaving the tetrahedron on. To find out what methane
is composed clicking on each atom. Remember you must click
at the ends of the
is composed of _____________.
**The chemical formula for methane would be _________.
the distance from carbon to each hydrogen?_________
**Measure the angles that form the tetrahedron?___
