Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Understand the Structure of $I_{3}^{-}$
- $I_{3}^{-}$ is a polyatomic ion consisting of three iodine atoms
- We need to determine the electron pair geometry around the central iodine atom
Step 3:: Determine the Central Atom's Electron Configuration
- The central iodine atom will have electron pairs around it - We need to count the total number of electron domains (bonding and non-bonding pairs)
Step 4:: Analyze the Electron Domain Arrangement
- In $I_{3}^{-}$, the central iodine has:
* Two single bonds (to the other iodine atoms) * One lone pair of electrons - Total electron domains = 3
Step 5:: Apply VSEPR Theory
- With 3 total electron domains, the electron pair geometry is trigonal planar - The bond angles will be approximately 120°
Final Answer
Key Concept: In VSEPR theory, the number of electron domains determines the electron pair geometry, regardless of whether these domains are bonding or non-bonding pairs.
