This worksheet challenges students to categorize physical and chemical properties as belonging to either metals or non-metals.

Let's complete the table by identifying whether each property is typical of metals or non-metals.

Here’s a summary of general physical and chemical properties:

Typical Properties of Metals:

- Shiny (metallic luster)
- Good conductors of electricity and heat
- High density
- Ductile (can be drawn into wires)
- Malleable (can be hammered into sheets)
- Sonorous (produce a ringing sound when struck)
- Oxides form alkaline solutions (basic)
- High melting and boiling points (generally)

Typical Properties of Non-Metals:

- Dull appearance (not shiny)
- Poor conductors of electricity and heat (insulators)
- Low density (generally)
- Brittle (if solid)
- Not sonorous
- Oxides form acidic solutions
- Can exist in all states (solid, liquid, gas)

Now, let’s fill in the table:

| Property | Metal or Non-Metal? |
|----------------------------------|---------------------|
| shiny | Metal |
| dull | Non-Metal |
| good conductor of electricity | Metal |
| poor conductor of electricity | Non-Metal |
| oxides form acidic solutions | Non-Metal |
| oxides form alkaline solutions | Metal |
| high density | Metal |
| low density | Non-Metal |
| ductile | Metal |
| malleable | Metal |
| brittle | Non-Metal |
| good conductor of heat | Metal |
| poor conductor of heat | Non-Metal |
| sonorous | Metal |
| not sonorous | Non-Metal |

Explanation of Key Points:

- Shiny vs. Dull: Metals have a characteristic metallic luster; non-metals are usually dull.
- Conductivity: Metals have free electrons that allow conduction of electricity and heat; non-metals lack this.
- Oxides: Metal oxides react with water to form bases (alkaline), while non-metal oxides form acids.
- Density: Metals tend to be dense due to closely packed atoms; non-metals are generally lighter.
- Ductility & Malleability: Metals can be shaped without breaking; non-metals are often brittle.
- Sonority: Metals produce sound when hit; non-metals do not.

✔ This classification helps distinguish metals from non-metals based on their physical and chemical behavior.
