Summary
Use the activity to build up the electronic configuration of the first 20 elements of the periodic table plus iron, copper and bromine as these are also included in most syllabuses. Display and use the data about the elements and their position in the periodic table to relate structure to properties and use these properties to make predictions about unfamiliar elements. Use the activities to reinforce previous learning about the elements and their atomic structure.
Suitable for
Years 10 and 11
Using a non-interactive whiteboard
All the features can be typed in or accessed via a mouse.
Prior learning required
- names and symbols of elements
- atomic structure including: sub-atomic particles, atomic number, mass number and electron configuration
Aims and objectives
For students to:
- relate position in the periodic table to electron configuration
- demonstrate similarities and differences of element properties related to their position in the periodic table
Timings
Can be used flexibly from 30 to 120 minutes.
Suggestions for group activities
Teachers may like to use group discussion to enable students to agree and justify their choices for the various predictive activities.
Suggestions for differentiation
There are no differentiated tasks within the activity. Differentiation would come from the complexity of the task determined by the teacher related to the ability of the groups of students.
Further activities
- demonstration of some of the elements
- investigation of properties, ie reactions with water, air and acid
- acidic/basic nature of the oxides of these elements related to their position in the periodic table
- displacement reactions for group VII
National curriculum links
Classifying materials: elements
Students should be taught:
- that elements can be represented
- that atoms consist of nuclei and electrons
- the charges and relative masses of protons, neutrons and electrons
- about mass number, atomic number and isotopes
- about a model of the way electrons are arranged in atoms for elements 1 to 20
- that the reactions of elements depend upon the arrangement of electrons in their atoms
Classifying materials: bonding
Students should be taught:
- that new substances are formed when atoms combine
- that chemical bonding can be explained in terms of the transfer or sharing of electrons
- how ions are formed when atoms gain or lose electrons
Changing materials: representing reactions
Students should be taught:
- to represent chemical reactions by word equations
- to represent reactions, including electrolytic reactions, by balanced equations using chemical symbols
Patterns of behaviour: the periodic table
Students should be taught:
- that the periodic table shows all elements, arranged in order of ascending atomic number
- the connection between the arrangement of outer electrons and the position of an element in the periodic table
- that elements in the same group of the periodic table have similar chemical properties
- that there is a gradual change in the properties of the elements from the top to the bottom of a group
- the properties and reactions of the alkali metals
- the properties, reactions and uses of the halogens
