Question 3

#### a. Write the name of the metal beside each of the following symbols:

- Au → Gold
*(From Latin "Aurum")*

- Pb → Lead
*(From Latin "Plumbum")*

- Al → Aluminum (or Aluminium)
*(Commonly used in both spellings, depending on region)*

- Fe → Iron
*(From Latin "Ferrum")*

- Na → Sodium
*(From Latin "Natrium")*

---

#### b. Write its chemical symbol beside each of the following metals:

- zinc → Zn
- magnesium → Mg
- copper → Cu
- silver → Ag
- calcium → Ca

> *Note: These are standard chemical symbols from the periodic table.*

Question 4

We are given two images (a and b) showing metals being used based on their physical properties. We need to:

1. Describe the use shown.
2. State which property or properties make it suitable.

Let’s analyze each one.

---

#### Image a: Pot with steam rising from it

- Describe the use:
The pot is being used for cooking. It heats up and transfers heat to the food or liquid inside.

- Property or properties:
Conductor of heat
Metals like aluminum or stainless steel are good conductors of heat, allowing them to efficiently transfer heat from the stove to the contents of the pot.

> ✔ So, the key property here is thermal conductivity.

#### Image b: Medal hanging on a ribbon

- Describe the use:
The medal is used as an award or decoration, likely worn around the neck.

- Property or properties:
Malleable and shiny (lustrous)
- Malleable: The metal can be hammered or pressed into thin sheets or intricate shapes (like the design on the medal).
- Lustrous: Metals have a shiny appearance, making them visually appealing for decorative purposes.

> ✔ Key properties: Malleability and Luster
