Activity 3: Metals, Nonmetals, and Metalloids Cut Off - Students color the periodic table and match properties to elements.

Since the image you've uploaded is a worksheet titled "Recall of Metals, Nonmetals and Metalloids", and it includes a blank periodic table, properties to cut out, and elements to classify, I will help you solve the activity step-by-step as if you were completing it.

🔍 Understanding the Task

This is an interactive classroom activity where students:
1. Color-code the periodic table based on element types.
2. Cut and paste elements into categories: Metals, Nonmetals, and Metalloids.
3. Match physical and chemical properties to each group.

Let’s go through each part of the activity and solve it logically.

## ✔ PART A: METALS, NONMETALS, AND METALLOIDS CUT OFF

🟡 Step 1: Color the Periodic Table

You are instructed to color the blank periodic table using:

- METALS → YELLOW
- NONMETALS → BLUE
- METALLOIDS → GREEN

#### 🌐 General Rules for Classification:
| Element Type | Location on Periodic Table |
|--------------|----------------------------|
| Metals | Left side (Groups 1–12), plus some in Group 13–16 (e.g., Sn, Pb) |
| Nonmetals | Right side (Groups 14–18), excluding metalloids |
| Metalloids | Diagonal line from B to Po (B, Si, Ge, As, Sb, Te) |

> Note: The full periodic table isn't shown here, but we can infer based on common knowledge.

So, when coloring:
- Yellow (Metals): Most of the left and center (except H).
- Blue (Nonmetals): Right side (C, N, O, F, P, S, Cl, etc.)
- Green (Metalloids): Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), Tellurium (Te)

> ⚠️ Note: Hydrogen (H) is a nonmetal but placed above alkali metals — treat it as nonmetal (blue).

✂️ Step 2 & 3: Cut Out and Paste Elements & Properties

Below the periodic table, there are:
- A list of elements (as letter tiles)
- A list of properties (in dashed boxes)

We need to:
1. Classify each element as metal, nonmetal, or metalloid
2. Assign correct properties to each group

---

## 🔤 Step 1: Identify Each Element

Given elements:
```
O, A, N, C, Si, Li, Si, B, Ir, Z,
B, Sr, T, F, S, H, P, S, X, G
```

Wait — these seem to be symbols, but some are letters like "A", "T", "X", "G"? That's likely a typo or misprint.

But looking closely:
These are probably element symbols, but some are abbreviations or codes?

Let’s check what makes sense.

Looking at the symbols:
- O = Oxygen (Nonmetal)
- N = Nitrogen (Nonmetal)
- C = Carbon (Nonmetal)
- Si = Silicon (Metalloid)
- Li = Lithium (Metal)
- B = Boron (Metalloid)
- Ir = Iridium (Metal)
- Z = ? → Probably Zn (Zinc), but written as Z? Or Zr? But only one letter → likely Zn (common metal)
- Sr = Strontium (Metal)
- F = Fluorine (Nonmetal)
- S = Sulfur (Nonmetal)
- H = Hydrogen (Nonmetal)
- P = Phosphorus (Nonmetal)
- X = ? → Possibly Xe (Xenon)? Or typo?
- G = ? → Possibly Ge (Germanium)? Or Ga (Gallium)?

But wait — this seems messy.

Actually, many of these are not real element symbols.

Let’s look again:

```
O A N C Si Li Si B Ir Z
B Sr T F S H P S X G
```

Possibly, the letters represent abbreviations or codes, but more likely, this is a set of element symbols with some typos or missing parts.

But notice: "A", "T", "X", "G" are not valid element symbols.

However, in many worksheets, especially for younger grades, they use letter codes that stand for elements.

Alternatively, maybe these are actual elements, and some are misprinted.

Let’s assume the following:
- “A” might be Al (Aluminum) → but written as A?
- “T” might be Ti (Titanium)?
- “X” could be Xe (Xenon)?
- “G” could be Ga (Gallium) or Ge (Germanium)?

But since "Si" appears twice, and "B" appears twice, perhaps duplicates are intentional.

Let’s try to interpret the real elements from the list:

✔ Valid element symbols present:
- O – Oxygen (Nonmetal)
- N – Nitrogen (Nonmetal)
- C – Carbon (Nonmetal)
- Si – Silicon (Metalloid)
- Li – Lithium (Metal)
- B – Boron (Metalloid)
- Ir – Iridium (Metal)
- Z – likely Zn (Zinc) → Metal
- Sr – Strontium (Metal)
- F – Fluorine (Nonmetal)
- S – Sulfur (Nonmetal)
- H – Hydrogen (Nonmetal)
- P – Phosphorus (Nonmetal)
- X – possibly Xe (Xenon) → Noble gas (Nonmetal)
- G – possibly Ge (Germanium) → Metalloid

But “A”, “T” don’t make sense.

Wait — maybe the letters are not elements, but property labels?

No — they are below the property boxes.

Wait — actually, let’s re-express the bottom section:

There are two rows of boxes:

```
[O] [A] [N] [C] [Si] [Li] [Si] [B] [Ir] [Z]
[B] [Sr] [T] [F] [S] [H] [P] [S] [X] [G]
```

These are likely element symbols, but with errors.

But “A” is not an element symbol.

Unless... it’s a typo, and should be Al (Aluminum)? But then why write just “A”?

Alternatively, maybe “A” stands for Argon? But Ar is symbol.

Wait — perhaps the “A” is meant to be “Al”, but printed incorrectly?

Similarly, “T” could be Ti (Titanium), “X” = Xe, “G” = Ge or Ga

Let’s assume the following corrections based on common elements and context:

| Symbol | Likely Element | Type |
|--------|----------------|------|
| O | Oxygen | Nonmetal |
| A | Al (Aluminum) | Metal |
| N | Nitrogen | Nonmetal |
| C | Carbon | Nonmetal |
| Si | Silicon | Metalloid |
| Li | Lithium | Metal |
| Si | Silicon | Metalloid |
| B | Boron | Metalloid |
| Ir | Iridium | Metal |
| Z | Zn (Zinc) | Metal |
| B | Boron | Metalloid |
| Sr | Strontium | Metal |
| T | Ti (Titanium) | Metal |
| F | Fluorine | Nonmetal |
| S | Sulfur | Nonmetal |
| H | Hydrogen | Nonmetal |
| P | Phosphorus | Nonmetal |
| S | Sulfur | Nonmetal |
| X | Xe (Xenon) | Nonmetal |
| G | Ge (Germanium) | Metalloid |

Now we have a complete list.

## 🧩 Step 2: Classify Elements

✔ Metals (YELLOW):

- Li (Lithium)
- Al (Aluminum) ← assumed from "A"
- Ir (Iridium)
- Zn (Zinc) ← assumed from "Z"
- Sr (Strontium)
- Ti (Titanium) ← assumed from "T"
- Fe? No — not listed. Wait, no iron.

List: Li, Al, Ir, Zn, Sr, Ti

> So metals: Li, Al, Ir, Zn, Sr, Ti

✔ Nonmetals (BLUE):

- O, N, C, F, S, H, P, Xe (X), S (again), O (again)

So: O, N, C, F, S, H, P, Xe

> Note: S appears twice — okay.

✔ Metalloids (GREEN):

- Si, B, Ge (from "G")

So: Si, B, Ge

> Also, note: "Si" appears twice, so two silicon tiles.

## 📝 Step 3: Properties to Match

The properties listed (dashed boxes):

```
LUSTER
SEMICONDUCT
HIGH
[blank]
[blank]
[blank]
[blank]
[blank]
```

And three columns (likely labeled):
- Left: Metals
- Middle: Nonmetals
- Right: Metalloids

But the columns aren't labeled yet — but based on standard science, we know:

🔹 Properties of Metals:

- Luster (shiny)
- Malleable (can be hammered)
- Ductile (can be drawn into wire)
- Good conductors of heat and electricity
- High density
- High melting point (usually)
- Solid at room temp (except Hg)

🔹 Properties of Nonmetals:

- Dull luster (not shiny)
- Brittle (if solid)
- Poor conductors (insulators)
- Low melting points (many)
- Gases, liquids, or brittle solids
- Not malleable

🔹 Properties of Metalloids:

- Intermediate properties
- Semiconductors (e.g., Si, Ge)
- Can be shiny or dull
- Some malleability
- Moderate conductivity

---

## 🎯 Now, Match Properties to Columns

We have these property words:

- LUSTER → Metals (shiny) → Left column
- MALLEABLE → Metals → Left column
- SEMICONDUCT → Metalloids → Right column
- HIGH → Could be high melting point, high density → Metals → Left column
- Other blanks: likely DUCTILE, CONDUCTOR, BRITTLE, INSULATOR, POOR CONDUCTOR, etc.

But since only some are given, we need to fill in based on typical properties.

Let’s assume the three columns are:

| Metals | Nonmetals | Metalloids |
|--------|-----------|------------|
| LUSTER | | |
| MALLEABLE | | |
| HIGH | | |
| | BRITTLE | |
| | INSULATOR | |
| | | SEMICONDUCT |
| | | |

But we must cut and paste the given terms.

Given terms to cut:
- LUSTER
- SEMICONDUCT
- HIGH
- MALLEABLE

And several blank boxes.

So likely:

✔ Column 1: METALS (YELLOW)

- LUSTER
- MALLEABLE
- HIGH (melting point/density)
- DUCTILE (possibly implied)
- GOOD CONDUCTOR (maybe missing)

But only LUSTER, MALLEABLE, and HIGH are provided.

So paste:
- LUSTER
- MALLEABLE
- HIGH

✔ Column 2: NONMETALS (BLUE)

- BRITTLE
- POOR CONDUCTOR
- INSULATOR
- DULL (luster)
- LOW (density/melting point)

But only one term is given: none directly.

Wait — the word "SEMICONDUCT" is under metalloids.

So likely, the middle column is nonmetals, and right is metalloids.

So:
- Middle column: Nonmetals → add BRITTLE, INSULATOR, DULL, etc.
- Right column: Metalloids → SEMICONDUCT

But the only given property for nonmetals is missing.

Wait — the only property labels given are:
- LUSTER
- SEMICONDUCT
- HIGH
- MALLEABLE

So assign:
- Metals: LUSTER, MALLEABLE, HIGH
- Metalloids: SEMICONDUCT
- Nonmetals: ??? — but nothing given

But there are blanks — so you may need to write or cut others.

But the instruction says: "Cut out the properties and the individual elements below and paste them"

So the properties are pre-printed in dashed boxes.

Let’s count the boxes:

There are 9 dashed boxes total:
- 3 with text: LUSTER, SEMICONDUCT, HIGH
- 1 with MALLEABLE
- 5 empty

Wait — actually:
- One box says LUSTER
- One says SEMICONDUCT
- One says HIGH
- One says MALLEABLE
- Then five blank ones

So four labeled, five blank.

So likely, the student must fill in the missing ones.

But since we're solving, let’s suggest the correct properties.

If you provide a scanned version or clarify the symbols (like whether "A" is Al, "T" is Ti, etc.), I can give exact placement.

But based on standard chemistry, this is the correct way to solve the activity.
