**Title: Understanding the Lewis Structure of IF2O2⁻ and Bond Angles**

### Lewis Structure Explanation

The Lewis structure provided illustrates the arrangement of atoms in the ion IF2O2⁻. In this structure:

- **Central Atom**: Iodine (I) is utilized as the central atom.
- **Atoms Surrounding Iodine**: Two fluorine (F) atoms and two oxygen (O) atoms surround the iodine atom.
- **Bonding and Lone Pairs**:
  - Iodine has a single bond with each fluorine atom, represented by a single line between I and F.
  - Iodine is double-bonded to each oxygen atom, indicated by two lines between I and O.
  - The lone pairs are shown with dots. Each fluorine and oxygen atom has three lone pairs, while iodine has two lone pairs.

### Ideal Bond Angles

The task involves determining the ideal bonding angle(s) of the central atom. The options provided are:

- **A) 109.5°**
- **B) 90° and 120°** (correct answer)
- **C) 120°**
- **D) 30°**
- **E) 135°**

The correct answer, which is highlighted, is **90° and 120°**. This indicates that the ideal bond angles in this molecular structure are a combination of these two angles, typical for molecules exhibiting characteristics of trigonal bipyramidal geometry.

### Educational Application

This detailed view into the Lewis structure of IF2O2⁻ provides students an opportunity to practice visualizing molecular geometry, formal charge minimization, and bond angle prediction based on electron pair geometry.

**Molecule Structure and Bonding Angles Explanation**

In the diagram, a molecule is depicted with an oxygen atom at the center, double-bonded to two other oxygen atoms, and single-bonded to two fluorine atoms. Each oxygen and fluorine atom has lone pairs denoted by dots surrounding them.

**Bond Angles:**
- Option B: 90° and 120°

**Feedback Guidance:**
You have submitted an unlikely resonance form of the required molecule or have not followed the specific instructions of the problem. 

**Correcting Structure Suggestions:**
Consider that more electronegative elements tend to prefer negative formal charges, while less electronegative elements prefer positive formal charges.
