Let's solve this step-by-step based on the image you've described. This is a science worksheet titled "ATOM LABEL AND DEFINE", where students are asked to:

1. Label parts of an atom diagram.
2. Define key atomic terms.

🔹 Step 1: Labeling the Atom Diagram

The diagram shows:
- A central cluster (the nucleus) made up of red and green spheres.
- Three orange spheres with a minus sign (–) orbiting around it on elliptical paths.

Based on standard atomic models:
- The orange spheres with negative signs are electrons.
- The central cluster contains protons (usually red or positive) and neutrons (usually green or neutral).
- The entire central region is called the nucleus.

So, we label the four blank boxes next to the diagram from top to bottom as follows:

1. Electron – points to one of the orbiting orange particles.
2. Orbit or Electron shell – refers to the path the electron follows (though not explicitly listed in the word bank, "Electron" is likely expected here).
- But since the word bank only includes: Protons, Neutrons, Electrons, Nucleus — we should use those.
- So the second box might be intended for Nucleus (pointing to the center), but let’s check the order.

Wait — looking at typical layout:

- The top arrow points to an electron.
- The second arrow points to the nucleus.
- The third arrow points to protons (inside the nucleus).
- The fourth arrow points to neutrons (also inside the nucleus).

But the arrows seem to point to:
1. One electron
2. The nucleus
3. Inside nucleus → protons
4. Inside nucleus → neutrons

So labeling from top to bottom:

1. Electron
2. Nucleus
3. Protons
4. Neutrons

✔ That matches the word bank.

🔹 Step 2: Definitions

Now fill in the definitions for each term.

| Term | Definition |
|------------|-----------|
| Nucleus | The central part of the atom that contains protons and neutrons. It holds most of the atom’s mass and is positively charged. |
| Protons | Positively charged particles found in the nucleus. The number of protons determines the atomic number of an element. |
| Neutrons | Neutral particles (no charge) found in the nucleus. They help stabilize the nucleus. |
| Electrons | Negatively charged particles that orbit the nucleus in energy levels or shells. They are involved in chemical bonding. |

✔ Final Answer

#### Label the Diagram (from top to bottom):
1. Electron
2. Nucleus
3. Protons
4. Neutrons

#### Definitions:

| Terms | Definition |
|------------|----------|
| Nucleus | The central core of an atom containing protons and neutrons; positively charged and dense. |
| Protons | Positively charged subatomic particles located in the nucleus; determine the atomic number. |
| Neutrons | Neutral subatomic particles in the nucleus; contribute to atomic mass but not charge. |
| Electrons | Negatively charged particles that move around the nucleus in orbits or shells; involved in chemical reactions. |
