Show Answer Key & Explanations Step-by-step solution for: 3.1 Basic Atomic Structure worksheet
Let's solve this step by step based on the diagram and the provided terms.

Objective:


Label the parts of the atom using the following terms:
- Proton
- Neutron
- Electron
- Nucleus
- Electron Cloud

---

Understanding the Diagram:



The image shows a simplified model of an atom:

1. Center cluster – Contains small circles with "+" signs and others without (neutral). This is the nucleus.
- The "+" signs represent protons (positively charged).
- The neutral circles represent neutrons (no charge).

2. Circles around the nucleus – These are electron shells or orbits.
- The small circles with "–" signs represent electrons (negatively charged).
- The region where electrons move is called the electron cloud.

3. Arrows point to specific parts, so we need to match each label correctly.

Step-by-step labeling:



#### 1. Top-right arrow points to an electron in orbit:
- This is a particle moving in a shell → Electron

#### 2. Left-side bracket points to the central cluster:
- This is the core of the atom → Nucleus

#### 3. Bottom-left arrow points to a circle inside the nucleus with a "+" sign:
- This is a positively charged particle → Proton

#### 4. Bottom-center arrow points to a circle inside the nucleus with no charge:
- This is a neutral particle → Neutron

#### 5. Large curved bracket on the right encloses all the electron orbits:
- This represents the region where electrons are found → Electron Cloud

---

Final Answer:



- Top-right box: Electron
- Left-side box (bracket): Nucleus
- Bottom-left box: Proton
- Bottom-center box: Neutron
- Right-side large box: Electron Cloud

---

🔍 Explanation:



- Protons and neutrons are located in the nucleus at the center.
- Electrons orbit the nucleus in energy levels (shells), forming the electron cloud.
- The electron cloud is not a solid structure but a region where electrons are likely to be found.

This model reflects the Bohr model of the atom, simplified for educational purposes.

All labels are now correctly assigned!
