Group 7 Elements and Atomic Structure Study Guide

A comprehensive examination guide covering group 7 elements periodic table GCSE topics and atomic structure models. The content explores physical properties of group 7 elements, their reactivity patterns, and the historical development of atomic models.

Key Points:

  • Detailed exploration of halogen states and properties
  • Analysis of group 7 elements reactivity patterns
  • Investigation of iron reactions with halogens
  • Evolution of atomic models from early theories to modern understanding

Page 4: Reaction of Iron with Chlorine

This page presents a question about the reaction between iron and chlorine:

  • Figure 1 shows the apparatus used for the investigation
  • Question 1.4 asks why the teacher conducted the experiment in a fume cupboard

Highlight: The question emphasizes safety considerations when working with chlorine gas, which is toxic.

Page 5: Mass Changes in Chemical Reactions

This page continues the iron and chlorine reaction question:

  • Provides the word equation for the reaction: iron + chlorine → iron chloride
  • Question 1.5 asks about the mass change during the reaction and requires an explanation

Example: The mass of the glass tube and contents would increase because the mass of chlorine gas is now included in the solid iron chloride product.

Page 6: Reactions with Other Group 7 Elements

This page extends the investigation to other Group 7 elements:

  • Table 2 shows observations for reactions between iron and chlorine, bromine, and iodine
  • Questions 1.6-1.8 cover predicting observations, balancing equations, and calculating relative formula mass

Vocabulary: Relative formula mass (Mr) - The sum of the relative atomic masses of all atoms in a formula.

Example: For FeBr3, Mr = 56 + (3 × 80) = 296

Page 7: Models of the Atom

This page begins a new question about atomic models:

  • Question 2.1 asks about the particle that changed the early "tiny sphere" model of the atom
  • Question 2.2 presents a diagram of the "plum pudding" model and asks for its name

Definition: Plum pudding model - An early model of the atom proposing that electrons were embedded in a positively charged "pudding".

Page 8: Development of Atomic Models

This page continues the atomic model questions:

  • Question 2.3 asks about the type of particle used in Rutherford's gold foil experiment
  • Question 2.4 asks which scientist first suggested electrons orbit the nucleus at specific distances

Highlight: These questions trace the historical development of our understanding of atomic structure.

AQA Please write clearly in block capitals. Centre number Surname Forename(s) Candidate signature GCSE CHEMISTRY Foundation Tier Le I declar

View

Page 9: Modern Atomic Model

This page concludes the atomic structure questions:

  • Mentions the three subatomic particles in the modern model: electrons, neutrons, and protons
  • Questions 2.5 and 2.6 ask about atomic number and mass number in relation to these particles

Definition: Atomic number - The number of protons in an atom's nucleus, which determines the element.

Definition: Mass number - The total number of protons and neutrons in an atom's nucleus.

Page 3: More Questions on Group 7 Elements

This page continues with questions about Group 7 elements:

  • Question 1.2 asks for the condensation temperature of chlorine gas
  • Question 1.3 requires completing sentences about trends in Group 7 melting points and intermolecular forces

Definition: Intermolecular forces - Attractive forces between molecules that affect physical properties like melting and boiling points.

Highlight: Going down Group 7, melting points increase due to stronger intermolecular forces between larger molecules.

Page 2: Question on Group 7 Elements

This page begins the first exam question about Group 7 elements in the periodic table:

  • Table 1 shows melting and boiling points of some Group 7 elements
  • Question 1.1 asks students to determine the state of bromine at 100°C based on the data

Example: For bromine, the melting point is -7°C and boiling point is 59°C, so at 100°C it would be a gas.

Vocabulary: Group 7 elements - The halogen group in the periodic table, including fluorine, chlorine, bromine, and iodine.

Modern Atomic Model

This section introduces the modern model of the atom with three subatomic particles: electrons, neutrons, and protons.

Key points:

  • Atoms of the same element have the same number of protons
  • Isotopes have different numbers of neutrons

Understanding the structure of atoms and the concept of isotopes is crucial for GCSE Chemistry students.
