Question

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.

Q1) Why are there more silicon relative to oxygen in Figure 2?

a. Figure 2 has more oxygen than figure 1

b. There are more silicon atoms in Figure 2 than in Figure 1

c. Polymerization has occurred in Figure 2, where the oxygen are being shared between tetrahedrons

d. In Figure 1, the oxygen are sharing with surrounding tetrahedrons

Q2) How many iron cations were you able to draw in for the single silicon-oxygen tetrahedron (Figure 1)?

a. One

b. Two

c. Three

d. Four

e. Five

Q3) Look at Figure 2. How many iron cations were you able to draw in for each silicon-oxygen tetrahedron (not the entire chain)? Choose a silicon-oxygen tetrahedron that is sitting in the middle of the chain, not the ends.

a. One

b. Two

c. Three

d. Four

e. Five

Q4) Which of the following minerals from the choices below share all oxygen in the silicate structure.

a. Quartz

b. Muscovite

c. Hornblende

d. Olivine

e. Pyroxene
