Step 1: Identify the central atom and its valence electron configuration in the ion I$^{- 3}$.
The central atom is Iodine (I), and its valence electrons are in the 5p orbital. Since the ion has a charge of - 3, we need to add three electrons to the neutral Iodine atom. This gives us a total of 8 electrons in the 5p orbital.
Step 2: Determine the number of electron domains around the central atom.
An electron domain is a region of space around an atom where electrons are likely to be found. In this case, we are considering the 5p orbital of Iodine, which already contains 8 electrons. Since each domain can hold up to 2 electrons (one pair), there will be 4 electron domains around the central atom.
Final Answer
Tetrahedral
