Part II – Silicate Structures
Below are two silicate structures.  Figure 1 is a single silicon oxygen tetrahedron.  Figure 2 is a single chain silicate showing the tetrahedrons are sharing oxygen atoms in their structure to create a chain.  Using these two images, answer the questions below.

Select one:

a. Figure 2 has more oxygen than figure 1
b. There are more silicon atoms in Figure 2 than in Figure 1

Print out the two figures above onto a piece of paper.   Draw an S on the oxygen that are being shared in the structure(s) above.  Then draw a black dot onto the oxygen that are not being shared to represent the iron atom attaching to that oxygen.  Once you have finished this, answer the following questions.  (Note:  when looking at the single chain, please note that there is an oxygen sitting on top of the silicon in addition to the three other oxygen next to the silicon.)
