Metals and non-metals interactive worksheet - Free Printable

Let's solve both parts of this worksheet step by step.

Question 1: Classify each description as Metal or Non-metal

We need to determine whether each description fits a metal or a non-metal, based on typical physical properties:

#### Key Properties:
- Metals: Shiny, solid (except mercury), good conductors of heat and electricity, malleable (flexible), ductile, often dense.
- Non-metals: Can be solids, liquids, or gases; often poor conductors; dull or colored; brittle (if solid); some are gases at room temperature.

Now let’s go through each:

---

a) Silvery solid that is a good conductor of heat.
✔ Metal – Metals are shiny and good conductors of heat.

b) Colourless gas.
✔ Non-metal – Gases like hydrogen, oxygen, nitrogen are non-metals.

c) Hard, strong but flexible solid.
✔ Metal – Metals like steel or iron are strong and malleable (flexible).

d) Dark coloured liquid that does not conduct electricity.
✔ Non-metal – Mercury is a liquid metal, but it conducts electricity. This one doesn't conduct → likely bromine, which is a dark red liquid non-metal.

e) Crumbly yellow solid.
✔ Non-metal – Sulfur is a yellow, crumbly solid non-metal.

f) Solid that is flexible and conducts electricity.
✔ Metal – Malleability + electrical conductivity = typical metal.

g) Solid that conducts electricity.
✔ Metal – Most conductive solids are metals. (Graphite is an exception, but it's a non-metal; however, the general case here points to metal.)

h) Green gas.
✔ Non-metal – Chlorine is a greenish-yellow gas, a non-metal.

i) Black dull solid.
✔ Non-metal – Iodine is a black solid, non-metal. Carbon (like graphite) is also black and dull.

j) Shiny solid that does not conduct electricity or heat well.
✔ Non-metal – Some non-metals like iodine can be shiny but are poor conductors. (Note: Most shiny solids that don’t conduct are non-metals.)

k) Shiny liquid that conducts electricity.
✔ Metal – Mercury is the only metal that is liquid at room temperature and conducts electricity.

| a | ☑️ | |
| b | | ☑️ |
| c | ☑️ | |
| d | | ☑️ |
| e | | ☑️ |
| f | ☑️ | |
| g | ☑️ | |
| h | | ☑️ |
| i | | ☑️ |
| j | | ☑️ |
| k | ☑️ | |

Question 2: Match Metal → Use → Property

We are given:
- Metals: Gold, Copper, Aluminium, Iron
- Uses: Road bridges, Phone cables, Jewellery, Cooking pots
- Properties: Conductor of heat, Strong, Conductor of electricity, Shiny

One link is already done:
- Gold → Jewellery → Shiny

Now let’s match the rest logically.

---

#### Copper
- Use: Phone cables → because copper is excellent at conducting electricity.
- Property: Conductor of electricity

✔ So: Copper → Phone cables → Conductor of electricity

---

#### Aluminium
- Use: Cooking pots → aluminium is lightweight and conducts heat well.
- Property: Conductor of heat

✔ So: Aluminium → Cooking pots → Conductor of heat

---

#### Iron
- Use: Road bridges → iron (or steel) is strong and used in construction.
- Property: Strong

✔ So: Iron → Road bridges → Strong

---

✔ Final Matching:

| Metal | Use | Property |
|----------|---------------|------------------------|
| Gold | Jewellery | Shiny |
| Copper | Phone cables | Conductor of electricity |
| Aluminium| Cooking pots | Conductor of heat |
| Iron | Road bridges | Strong |

---

🔗 Draw the lines:

- Gold → Jewellery → Shiny (already done)
- Copper → Phone cables → Conductor of electricity
- Aluminium → Cooking pots → Conductor of heat
- Iron → Road bridges → Strong
