**Understanding Lewis Representations**

The Lewis representation above illustrates a chemical reaction between a halogen (depicted in blue) and a main-group element from group _____ (depicted in red).

**Key Concepts:**

1. **Octet Rule**: In this representation, each Y atom requires _____ electron(s) to achieve a complete octet. This is achieved by forming _____ bond(s) with atoms of X.

2. **Electron Pairs**:
   - **Unshared Electron Pairs**: These are lone pairs of electrons not involved in bonding.
   - **Bonding Electron Pairs**: These are shared between atoms to form covalent bonds.

3. **Bonds**: The bonds formed in the product molecule are _____.

4. **Product Structure**: 
   - The diagram on the left shows individual atoms of X and Y before forming bonds.
   - In the product on the right, Y atoms are surrounded by electron pairs, which include shared pairs with X atoms indicating bond formation.

---

**Interactive Exercise**: 

- Use the reference materials to identify the specific group for the main-group element and determine the number of bonds and electron pairs.
- Complete the sentences with the correct values to gain a deeper understanding of electron sharing and bond formation.

### Covalent Bonding: Lewis Structures and Electron Pairing

#### Diagram Explanation

The image shows a chemical reaction using Lewis structures. 

- **Reactants:** 
  - On the left is a halogen element (blue) represented by the symbol **X** with 7 valence electrons (dots around it) and a main-group element from group (red) represented by the symbol **Y** with dots indicating valence electrons. 

- **Product:** 
  - On the right, the product is a molecule where X and Y are bonded, with a complete octet and shared electron pairs depicted.

#### Description

The diagram displays a reaction between:
- **A halogen (X)** in blue
- **A main-group element from group (Y)** in red

### Fill in the Details

1. The Y atom needs \(\_\_\_\_\_\) electron(s) to complete its octet and gains these electrons by forming \(\_\_\_\_\_\) bond(s) with atoms of X.

2. There are \(\_\_\_\_\_\) total electron pair(s) and \(\_\_\_\_\_\) bonding electron pair(s) in the product molecule.

### Actions

- Use the dropdown menu to select the correct group number for the main-group element Y.
- Fill in the blanks to accurately describe the bonding details for the Y atom.

#### Options

- Dropdown options for selecting Y element’s group: 1A, 2A, 3A, 4A, 5A, 6A
- Input fields for answering the questions about electron requirements and bonding.

### Interaction

- **Submit Answer**: To check the response.
- **Retry Entire Group**: To attempt again, with 8 more attempts remaining.

This exercise helps in understanding the concepts of octet completion and electron sharing in covalent compounds.
