🔬 Part 1: Element Properties Knowledge

1. Circle the properties that describe METALS:

Shiny appearance

Good conductors of electricity

Brittle when solid

Malleable (can be hammered into shapes)

Poor conductors of heat

Ductile (can be drawn into wires)

2. Which group of elements has mixed properties and are often used as semiconductors?

Metals

Nonmetals

Metalloids

Noble gases

3. Complete the sentence: Nonmetals are usually ________ conductors of electricity and have a ________ appearance.

Nonmetals are usually _____________ conductors of electricity and have a _____________ appearance.

📊 Part 2: Element Classification Challenge

4. Classify each element as Metal (M), Nonmetal (N), or Metalloid (Mt). Write your answer in the space provided:

Iron (Fe): _______ Hint: Used to make steel, magnetic, conducts electricity

Oxygen (O): _______ Hint: Gas at room temperature, essential for breathing

Silicon (Si): _______ Hint: Used in computer chips, semiconductor properties

Carbon (C): _______ Hint: Forms diamonds and graphite, poor conductor as diamond

Aluminium (Al): _______ Hint: Used in foil and cans, lightweight and shiny

Boron (B): _______ Hint: Has properties between metals and nonmetals

5. Choose ONE element from question 4 and explain why you classified it as you did. Give at least TWO properties that support your classification:

🔗 Part 3: Matching Properties to Groups

6. Match each property to the correct element group by drawing lines:

1. Usually gases or brittle solids

2. Excellent heat conductors

3. Used in electronic devices

4. Can be hammered into thin sheets

5. Dull appearance

6. Mixed conducting properties

A. Metals

B. Nonmetals

C. Metalloids

D. Metals

E. Nonmetals

F. Metalloids

🌍 Part 4: Real-World Applications

7. For each everyday item, identify what type of element it primarily contains and explain why that element type is suitable:

Cooking pot: Element type: ____________

Why suitable: _________________________________________________

Computer microchip: Element type: ____________

Why suitable: _________________________________________________

Balloon gas (helium): Element type: ____________

Why suitable: _________________________________________________

8. Think of your own example! Name one item you use regularly and identify what type of element it contains:

9. Reflection: Why is it important for scientists to classify elements into groups? Write 2-3 sentences:
