Let's solve this step-by-step based on the image you've provided, which is a worksheet titled
"Your Guide to The Atom". It includes a diagram of an atom, a table of subatomic particles, and some fill-in-the-blank questions.
---
🔬 Step 1: Identify the parts of the atom in the diagram
The diagram shows:
- A central nucleus with red and green spheres.
- Blue spheres orbiting around the nucleus in two shells (energy levels).
- Arrows pointing to different parts with blank boxes.
We'll label each part:
####
✔ Labels for the diagram:
-
Red spheres in the nucleus →
Protons
(They have a positive charge and are found in the nucleus.)
-
Green spheres in the nucleus →
Neutrons
(Neutral charge, also in the nucleus.)
-
Blue spheres in orbits →
Electrons
(Negative charge, orbit the nucleus.)
So, labeling the blanks around the diagram:
1.
Top-left arrow pointing to outermost electron shell →
Electron Shell / Energy Level
2.
Left arrow pointing to electron →
Electron
3.
Bottom-left arrow pointing to inner shell →
Electron Shell / Energy Level
4.
Right arrow pointing to proton →
Proton
5.
Bottom-right arrow pointing to neutron →
Neutron
6.
Top-right arrow pointing to electron →
Electron
> So, the labels should be:
> - Top-left:
Electron Shell
> - Left:
Electron
> - Bottom-left:
Electron Shell
> - Right:
Proton
> - Bottom-right:
Neutron
> - Top-right:
Electron

🧪 Step 2: Fill in the table: Particle, Charge, Location
| Particle | Charge | Location in atom |
|---------|--------|------------------|
| Electron | -1 | Electron Shell |
| Neutron | 0 | Nucleus |
| Proton | +1 | Nucleus |
> So, fill the table as:
> - First row:
Electron, -1,
Electron Shell
> - Second row:
Neutron, 0,
Nucleus
> - Third row:
Proton, +1,
Nucleus

🔢 Step 3: Atomic Number Explanation
It says:
> "The Atomic Number – which is the number of __________. This number is also equal to the number of __________."
From the box showing
3 and
Li, we know:
-
Atomic number = 3
-
Element = Lithium (Li)
So:
- Atomic number = number of
protons
- Also equals number of
electrons in a neutral atom
✔ Fill in:
> The Atomic Number – which is the number of
protons.
> This number is also equal to the number of
electrons.

⚛️ Step 4: Atomic Symbol
Given:
- Atomic number: 3
- Element: Li (Lithium)
So,
Atomic Symbol:
Li
> Fill in:
Li
---
💡 Step 5: Final Sentence
> "The number of __________ determines the type of element."
Answer:
Protons
Because the number of protons (atomic number) defines the element.
✔ Fill in:
protons

✔ Final Answers Summary:
#### Diagram Labels:
- Top-left:
Electron Shell
- Left:
Electron
- Bottom-left:
Electron Shell
- Right:
Proton
- Bottom-right:
Neutron
- Top-right:
Electron
#### Table:
| Particle | Charge | Location in atom |
|------------|--------|----------------------|
| Electron | -1 | Electron Shell |
| Neutron | 0 | Nucleus |
| Proton | +1 | Nucleus |
#### Atomic Number Box:
> The Atomic Number – which is the number of
protons.
> This number is also equal to the number of
electrons.
#### Atomic Symbol:
>
Li
#### Last sentence:
> The number of
protons determines the type of element.
