3-part question.

For the molecule, SeI₄: 1. **Draw the Lewis structure then state the molecular arrangement and shape.** 2. **Identify the hybrid that the central atom uses.** 3. **Draw the orbital diagram for the ground state, excited state (if needed), and the hybrid.** **Explanation:** 1. **Lewis Structure and Molecular Shape:** - Begin by drawing the Lewis structure, which represents the valence electrons and bonds present in the SeI₄ molecule. This involves placing Se (selenium) at the center with four iodine (I) atoms surrounding it, along with the lone pairs on Se. - Determine the molecular arrangement and shape based on the VSEPR (Valence Shell Electron Pair Repulsion) theory. Consider the effects of lone pairs and bonded pairs to predict the geometry. 2. **Hybridization:** - Identify the type of hybridization that the central atom (Se) undergoes. This requires analyzing the bonding and coordination number around Se to determine the mixing of atomic orbitals. 3. **Orbital Diagrams:** - Construct orbital diagrams showing electron configurations for: - The ground state, where electrons occupy the lowest energy orbitals available. - The excited state (if applicable), where electrons may jump to higher energy levels. - The hybrid state, which demonstrates the formation of hybrid orbitals (such as sp³, sp², etc.) that accommodate bonding and lone pairs. These steps help in visualizing the chemical properties and bonding of SeI₄ for educational purposes.
