Group 7 Elements-The Halogens -properties, reactions and trends.

Student workbook and teacher PP for investigating and explaining the trends in Group 7 -Halogens. Could be used for GCSE and AS level (&extension for KS3).
The workbook captures the key points on the physical and chemical properties of G 7 elements, including the displacement reactions of the halogens.
At the end of these lesson students should be able to:
a) Describe the characteristics of G7 elements
b) Describe the trends in melting, boiling points of G7
c) Describe the reactions of G7 with hydrogen and metals (observations- video)
d) Describe the trend in reactivity of G7
e) Explain the trend in reactivity of G7 in terms of how easily the atom gains an extra electron to obtain a stable electronic configuration (size of atoms- distance of the outer shell from the nucleus, shielding of the nuclear charge, nuclear attraction for the outer shell - are considered).
f) Describe and explain the Displacement reactions of the halogens.
g) Compare and contrast the trends in the properties of G1 &G7.

The workbook contains different types of activities and assessment questions (recall and application questions) that will allow students to gain the knowledge and apply it to check / assess their learning. The PP supports the workbook.
