Educational worksheet for identifying metals and non-metals based on properties and common items.

Let's solve the worksheet step by step.

II. The following properties to be marked as metal or non-metal

We need to identify whether each property is typical of metals or non-metals.

| Property | Metal | Non-metal |
|--------|-------|-----------|
| 1. I shine when I'm polished | ✔ | ✘ |
| 2. I can be broken down to a powdery substance on tapping down | ✘ | ✔ |
| 3. I am sonorous and produce ringing sound on hitting | ✔ | ✘ |
| 4. I am not lustrous | ✘ | ✔ |
| 5. I am a bad conductor of electricity and heat | ✘ | ✔ |

#### Explanation:
1. Shine when polished → Metals are lustrous (shiny), especially when polished.
→ Metal

2. Broken down to powder on tapping → This describes brittleness, which is a property of non-metals.
→ Non-metal

3. Sonorous (produces ringing sound) → Metals produce a ringing sound when struck.
→ Metal

4. Not lustrous → Lack of shine is typical of non-metals.
→ Non-metal

5. Bad conductor of electricity and heat → Non-metals are generally poor conductors.
→ Non-metal

III. The following list of items to be marked as metal or non-metal

Now classify the items:

| ITEM | METAL | NON-METAL |
|------|-------|-----------|
| 🟦 Water bottle (plastic) | ✘ | ✔ |
| 💍 Gold rings | ✔ | ✘ |
| 💎 Diamond | ✘ | ✔ |
| 🔪 Kitchen utensils (pots, pans) | ✔ | ✘ |

#### Explanation:
1. Water bottle (plastic) → Made of plastic, which is a non-metal.
→ Non-metal

2. Gold rings → Gold is a metal.
→ Metal

3. Diamond → A form of carbon, which is a non-metal.
→ Non-metal

4. Kitchen utensils (pots, pans) → Typically made of steel, aluminum, etc., all metals.
→ Metal

✔ Final Answer Table:

#### II. Properties

| Property | Metal | Non-metal |
|--------|-------|-----------|
| 1. I shine when I'm polished | ✔ | ✘ |
| 2. I can be broken down to a powdery substance on tapping down | ✘ | ✔ |
| 3. I am sonorous and produce ringing sound on hitting | ✔ | ✘ |
| 4. I am not lustrous | ✘ | ✔ |
| 5. I am a bad conductor of electricity and heat | ✘ | ✔ |

#### III. Items

| ITEM | METAL | NON-METAL |
|------|-------|-----------|
| Water bottle | ✘ | ✔ |
| Gold rings | ✔ | ✘ |
| Diamond | ✘ | ✔ |
| Kitchen utensils | ✔ | ✘ |

---

✔ Summary:
- Metals are shiny, sonorous, malleable, good conductors, and ductile.
- Non-metals are dull, brittle, poor conductors, and often gases or solids that break easily.

This classification helps in identifying materials based on their physical and chemical behavior.
