iGCSE Chemistry Multiple Choice (Extended) : 8.3 Group VII properties: Exam Style Questions Paper 2

Question

Some information about an element from Group VII of the Periodic Table is shown.

melting point/°C	–7
boiling point/°C	59

What is the element?

A) fluorine
B) chlorine
C) bromine
D) iodine

▶️ Answer/Explanation

Solution

Ans: C

To identify the element from Group VII (halogens) with these properties:

1. Fluorine (F) has mp = -220°C and bp = -188°C – too low

2. Chlorine (Cl) has mp = -101°C and bp = -34°C – too low

3. Bromine (Br) has mp = -7°C and bp = 59°C – matches exactly

4. Iodine (I) has mp = 114°C and bp = 184°C – too high

The melting and boiling points increase down Group VII. Bromine is the only halogen that is liquid near room temperature, with these specific values.

Question

Fluorine is the element at the top of Group VII of the Periodic Table.

Which statement describes fluorine?

A) It is inert.
B) It is monatomic.
C) It is non-metallic.
D) It is a solid at room temperature.

▶️ Answer/Explanation

Solution

Ans: C

Fluorine is a highly reactive non-metallic element (option C). It is not inert (A is wrong), exists as diatomic F₂ molecules (B is wrong), and is a pale yellow gas at room temperature (D is wrong). As a halogen, fluorine is one of the most reactive elements in the periodic table.

Question

Group VII elements show trends in their physical properties going down the group.

Answer/Explanation

Ans: B

Question

Which statement about elements in Group I and Group VII of the Periodic Table is correct?

A. Bromine reacts with potassium chloride to produce chlorine.
B. Iodine is a monatomic non-metal.
C. Lithium has a higher melting point than potassium.
D. Sodium is more reactive with water than potassium.
