What you need to know
13 objective pages available
Properties of Groups 1, 7, and 0 Elements1 objectives
- Retrieve and apply knowledge of the simple properties of Groups 1, 7 and 0.
How Outer Shell Electrons Determine Group 1, 7 and 0 Properties and Trends1 objectives
- Account for the way observed simple properties of Groups 1, 7 and 0 depend on the outer shell of electrons of the atoms and predict properties from given trends down the groups.
Properties and Uses of Transition Metals1 objectives
- Retrieve and apply knowledge of the general properties of transition metals and their compounds and exemplify these by reference to a small number of transition metals.
Predicting Reactivity from Periodic Table Position1 objectives
- Use evidence to predict possible reactions and probable reactivity of elements from their positions in the Periodic Table.
Metal Reactivity and Ion Formation1 objectives
- Account for the way the reactivity of metals with water or dilute acids is related to the tendency of the metal to form its positive ion.
Establishing a Metal Reactivity Series from Experiments1 objectives
- Develop knowledge and skill in an order of reactivity of metals based on experimental results.
Identifying Common Gases: Tests and Observations1 objectives
- Communicate the key features of tests to identify selected gases.

- Recognise species from test results.
Understanding Flame Tests for Metal Ion Identification1 objectives
- Draw supported meaning from flame tests to identify metal ions.
Advantages of Instrumental Methods of Analysis1 objectives
- Communicate the key features of the advantages of instrumental methods of analysis.
Interpreting Instrumental Results1 objectives
- Draw supported meaning from an instrumental result given appropriate data in chart or tabular form, when accompanied by a reference set of data in the same form.

Practice preview
- When iron metal is placed in copper(II) sulfate solution, a brown solid forms on the surface of the iron. This observation suggests that:
- An unknown element, X, is found to be in the same group as fluorine (F) and chlorine (Cl). It is positioned below bromine (Br). a) Name the group that element X is in. b) Predict the reactivity of element X compared to bromine. Justify your answer in terms of electron attraction. [4 marks]
- Describe the complete method for carrying out a flame test to identify a metal ion from a solid sample. Include any necessary safety precautions. [6 marks]
