Assignment title Assignment 3: Electronic Structure and the Periodic Table (P3, P4, M3, M4, D2)
The purpose of this assignment is to:
Enable you to appreciate how the reactivity of elements is related to their electronic configuration
Scenario
Ms Longhurst has asked BTec students to create a presentation for the open day; your mission is to
provide an explanation of the reactivity of elements in relation to their electronic structure.
Task 1
Fill in pages 1 to 3 of the atomic structure sheets provided from your assessor.
This provides evidence for P3
Task 2
Fill in a results table for the experiments you will see as demonstrations, and do, using the alkali metals and
halogens. The methods for the displacement reactions you will be experiencing will be given to you.
This provides evidence for P4
Task 3
Make use of your copy of the periodic table to look up the atomic numbers for the elements in group 1 and
group 7.
Using this information now draw atoms Lithium to Rubidium from the group1 alkali metals, and Fluorine to
Iodine from the group 7 halogens, displaying the correct electronic arrangements.
Use these diagrams to describe any patterns in size and electron arrangements you see in these groups.
This provides evidence for M3
Task 4
Your experimental results should enable you to explain why the elements of groups 1 and 7 are mostly used
in the form of compounds, not as elements.
This provides evidence for M4
Task 5
Explain in your own words how the elements Li to Rb react according to their atomic structure and repeat
this explanation for group 7 F to I.
This provides evidence for D2
