Silicon is a micromineral needed for the growth of bones, tendons, and ligaments. Draw or write each of the following for silicon:
a. orbital diagram b. abbreviated orbital diagram
c. electron configuration d. abbreviated electron configuration
Table 1
a. From the periodic table, we see that Si, with atomic number 14, has 14 electrons. Place two electrons in each orbital, and single electrons in the highest energy level.
