It looks like you've uploaded a
blank periodic table with the categories labeled:
Metals,
Metalloids, and
Nonmetals. The task likely involves identifying or coloring in elements based on their classification, but since no specific question is stated, I'll assume your goal is to understand how to classify elements on this periodic table using the provided color coding.
Let’s go through the
solution and
explanation:
---
🔍 Understanding the Periodic Table Classification
The periodic table is divided into three main categories:
1.
Metals – Shown in
light blue
2.
Metalloids – Shown in
green
3.
Nonmetals – Shown in
orange
These classifications are based on physical and chemical properties.

🧩 Where Are Each Type Located?
####
✔ Metals (Light Blue)
- Found on the
left side and
center of the periodic table.
- Includes:
-
Alkali metals (Group 1, except hydrogen)
-
Alkaline earth metals (Group 2)
-
Transition metals (Groups 3–12)
-
Post-transition metals (e.g., Sn, Pb, Bi)
-
Lanthanides and Actinides (bottom two rows)
> ❗ Note: Hydrogen (H), although in Group 1, is a
nonmetal and is not classified as a metal.
####
✔ Metalloids (Green)
- Form a
diagonal staircase from
Boron (B) to
Polonium (Po).
- Elements:
B, Si, Ge, As, Sb, Te, Po
- These have properties intermediate between metals and nonmetals.
####
✔ Nonmetals (Orange)
- Found on the
right side of the periodic table.
- Includes:
-
Halogens (Group 17): F, Cl, Br, I, At
-
Noble gases (Group 18): He, Ne, Ar, Kr, Xe, Rn
- Other nonmetals: C, N, O, P, S, Se
> ⚠️ Hydrogen (H) is a
nonmetal, even though it's in Group 1.

✔ How to Solve This Task
If the task is to
fill in the periodic table with element symbols and classify them correctly:
#### Step-by-Step Guide:
1.
Identify each element's position by atomic number or symbol.
2.
Color or label each box based on its category:
- Light blue → Metal
- Green → Metalloid
- Orange → Nonmetal
3. Use the
staircase line as a guide:
- Elements
to the left of the staircase are
metals.
- Elements
on the staircase are
metalloids.
- Elements
to the right are
nonmetals.

🧪 Example Classifications
| Element | Group | Classification |
|--------|-------|----------------|
| Na | 1 | Metal |
| Fe | 8 | Metal |
| Si | 14 | Metalloid |
| O | 16 | Nonmetal |
| Cl | 17 | Nonmetal |
| H | 1 | Nonmetal |

💡 Final Answer Summary
To complete the task:
-
Fill in the periodic table with correct element symbols.
-
Color-code each box:
-
Blue: Metals (most of the table)
-
Green: Metalloids (B, Si, Ge, As, Sb, Te, Po)
-
Orange: Nonmetals (right side, including H, C, N, O, P, S, etc.)
This classification reflects the
trends in electronegativity, conductivity, and reactivity across the periodic table.

If you have a
specific question about this image (e.g., "Which element is a metalloid in period 3?" or "Why is hydrogen a nonmetal?"), feel free to ask!
Parent Tip: Review the logic above to help your child master the concept of periodic table of the elements worksheet.
