**Molecular Models and Ions: Understanding the Structures**

In this section, we explore the structural models of two different ions, comparing their molecular geometries and compositions. 

### Model 1: Chlorate Ion

**Image Description:**
- **Model Type:** Ball & Stick
- **Description:** The model shows a molecule with three atoms: one large red atom labeled "O" (oxygen) and one smaller green atom labeled "Cl" (chlorine). The atoms are connected by sticks representing bonds. 
- **Configuration:** Oxygen and Chlorine are connected linearly.

**Molecular Formula:**
\[ \_\_\_\_\_\ ]

**Name:**
\[ \_\_\_\_\_\ ] ion

### Model 2: Sulfate Ion

**Image Description:**
- **Model Type:** Ball & Stick
- **Description:** This model represents a more complex structure involving four red atoms labeled "O" (oxygen) and a yellow atom labeled "S" (sulfur) at the center. The sulfur atom is bonded to each of the four oxygen atoms. 
- **Configuration:** The structure has a tetrahedral arrangement, with the sulfur atom at the center and the oxygen atoms positioned symmetrically around it.

**Molecular Formula:**
\[ \_\_\_\_\_\ ]

**Name:**
\[ \_\_\_\_\_\ ] ion

### Key Questions:
1. Identify the chemical formulas based on the structural models provided.
2. Provide the proper names for each ion depicted.

**Hints:**
- For the first model, recall that the combination of chlorine and oxygen typically forms a chlorate ion.
- For the second model, remember that the tetrahedral arrangement with sulfur and oxygen atoms often forms a sulfate ion.

Analyzing molecular models, like the ones shown, helps in understanding the spatial arrangement of atoms and the structure-function relationship in chemical compounds.
