Problem Analysis:

The task involves identifying and counting the number of electrons, protons, and neutrons in various atomic models. Each model is represented by a diagram showing protons (red circles), neutrons (blue circles), and electrons (black dots). The goal is to analyze each diagram and fill in the corresponding values for protons, neutrons, and electrons.

Solution Approach:

1. Identify Protons: Protons are positively charged particles located in the nucleus. They are represented by red circles.
2. Identify Neutrons: Neutrons are neutral particles located in the nucleus. They are represented by blue circles.
3. Identify Electrons: Electrons are negatively charged particles that orbit the nucleus. They are represented by black dots.
4. Count Each Particle: Carefully count the number of red circles (protons), blue circles (neutrons), and black dots (electrons) in each diagram.
5. Fill in the Table: Use the counts to fill in the table provided in the image.

Step-by-Step Solution:

#### Diagram 1:
- Protons: 6 red circles
- Neutrons: 6 blue circles
- Electrons: 6 black dots

#### Diagram 2:
- Protons: 8 red circles
- Neutrons: 8 blue circles
- Electrons: 8 black dots

#### Diagram 3:
- Protons: 7 red circles
- Neutrons: 7 blue circles
- Electrons: 7 black dots

#### Diagram 4:
- Protons: 9 red circles
- Neutrons: 9 blue circles
- Electrons: 9 black dots

#### Diagram 5:
- Protons: 5 red circles
- Neutrons: 5 blue circles
- Electrons: 5 black dots

#### Diagram 6:
- Protons: 10 red circles
- Neutrons: 10 blue circles
- Electrons: 10 black dots

#### Diagram 7:
- Protons: 4 red circles
- Neutrons: 4 blue circles
- Electrons: 4 black dots

#### Diagram 8:
- Protons: 3 red circles
- Neutrons: 3 blue circles
- Electrons: 3 black dots

Filling in the Table:

Using the counts from each diagram, we can fill in the table as follows:

| Diagram | Protons | Neutrons | Electrons |
|---------|---------|----------|-----------|
| 1 | 6 | 6 | 6 |
| 2 | 8 | 8 | 8 |
| 3 | 7 | 7 | 7 |
| 4 | 9 | 9 | 9 |
| 5 | 5 | 5 | 5 |
| 6 | 10 | 10 | 10 |
| 7 | 4 | 4 | 4 |
| 8 | 3 | 3 | 3 |

Final Answer:

\[
\boxed{
\begin{array}{|c|c|c|c|}
\hline
\text{Diagram} & \text{Protons} & \text{Neutrons} & \text{Electrons} \\
\hline
1 & 6 & 6 & 6 \\
2 & 8 & 8 & 8 \\
3 & 7 & 7 & 7 \\
4 & 9 & 9 & 9 \\
5 & 5 & 5 & 5 \\
6 & 10 & 10 & 10 \\
7 & 4 & 4 & 4 \\
8 & 3 & 3 & 3 \\
\hline
\end{array}
}
