  1. 1. Assignment front sheet Learner name Assessor name Date issued Completion date Submitted on Qualification Unit number and title Level 2 BTEC First Certificate in Applied Science Unit 1 Chemistry and Our Earth Assignment title Assignment 3: Electronic Structure and the Periodic Table (P3, P4, M3, M4, D2) In this assessment you will have opportunities to provide evidence against the following criteria. Indicate the page numbers where the evidence can be found. Criteria reference To achieve the criteria the evidence must show that the student is able to: Task no. Page numbers P3 Describe atomic structures of elements 1-20, found in the periodic table 1 P4 Carry out an investigation into the chemical properties of elements in groups 1 and 7 2 M3 Describe the trends within the atomic structure of groups 1 and 7 in the periodic table 3 M4 Explain why the elements of groups 1 and 7 are mostly used in the form of compounds 4 D2 Explain the trends in the chemical behaviour of the elements of groups 1 and 7 in relation to their electronic structure 5 Learner declaration I certify that the work submitted for this assignment is my own and research sources are fully acknowledged.

  2. 2. Assignment brief Unit number and title Unit 1 Chemistry and Our Earth Qualification Level 2 BTEC First Certificate in Applied Science Start date Deadline date Assessor 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 Sources of information Textbooks Beech J, Milward C and Sochacki F – BTEC Level 2 First Applied Science ActiveTeach CD ROM (Pearson, 2010) ISBN 9781846906114 Brain C, Goodfellow D, Hocking S, Llewellyn R, Kitchin C, Mathews J, Musa 1 and Rhodes P – BTEC Level 2 First Applied Science Student Book (Pearson, 2010) ISBN 9781846906091
