Student Information

Part A: Physical Properties 9 marks

Instructions: Complete the table below to compare the general physical properties of metals and non-metals. Use words like high, low, good, poor, yes, or no.

Property Metals Non-Metals
Thermal Conductivity
Electrical Conductivity
Malleability (Can it be hammered into sheets?)
Ductility (Can it be drawn into wires?)
Typical Melting & Boiling Points

Challenge Questions:

1. Copper is used for electrical wiring. Which two properties from the table make it suitable for this purpose?

2. Aluminium is used to make kitchen foil. Which property does this demonstrate?

3. Iodine is a shiny, grey solid but it is a non-metal. Tungsten has a very high melting point and is used in light bulb filaments. What do these examples tell you about the properties of elements?

Part B: Chemical Reactions 11 marks

Instructions: Complete the word equations and symbol equations for the following reactions.

Reaction with Dilute Acids

Metals above hydrogen in the reactivity series react with dilute acids to produce a salt and hydrogen gas.

General Word Equation: Metal + Acid → +

Specific Examples:

1. Magnesium + Hydrochloric Acid →

Word Equation:

Symbol Equation:

2. Zinc + Sulfuric Acid →

Word Equation:

Symbol Equation:

Reaction with Water and Steam

The reactivity of the metal determines the reaction.

With Cold Water: Very reactive metals (e.g., Potassium, Sodium, Calcium) react with cold water to form a metal hydroxide and hydrogen gas.

Metal + Water → +

With Steam: Less reactive metals (e.g., Magnesium, Zinc, Iron) react with steam to form a metal oxide and hydrogen gas.

Metal + Steam → +

Specific Examples:

1. Calcium + Cold Water →

Word Equation:

2. Zinc + Steam →

Word Equation:

Final Thought:

Why do you think gold and silver are often found as native metals (pure elements) in the Earth's crust, while metals like sodium or iron are always found in compounds?
