Assessment Issue
Date
You are a supervisor in an industrial laboratory.
The company you work for produces large amounts of solutions that are sold to schools, colleges, academies and smaller
laboratories. They have also started a work experience program to give sixth form students an insight into the industry and
to offer those with scientific potential jobs for after they finish their exams.
The company has asked you to produce an induction pack for the work experience students that could also be sent to
schools to boost the profile of the company.
Syllabus
The periodic table: organisation of elements; periodicity; groups (physical and chemical properties); relative atomic mass;
atomic number
Electronic structure of atoms: Bohr’s theory
Bonding of elements: ionic bonding; covalent bonding; tetrahedral basis of organic chemistry
Quantities in chemical reactions: formulae; balanced equations; relative molecular mass; moles; molar masses;
molarities; preparation of standard solutions and titrations
Criteria
P1: Outline the key features of the periodic table, atomic structure and chemical bonding
For P1, learners must outline the periodic table, the electronic structure of atoms and the bonding of atoms.
P2: Demonstrate practically the ability to prepare chemical solutions and test their accuracy
For P2, learners must demonstrate practically the ability to prepare standard solutions and test their accuracy by
titration. Learners must write balanced chemical equations from the results they generate. The quantities in chemical
reactions must also be calculated accurately. Lengthy descriptions of the quantities in which chemical systems react
are not required for P2. Tutors should complete observation forms as evidence of learners demonstrating required
practical skills.
M1: Relate the key features of the periodic table to the conclusions drawn from the practical activities
M1, learners must draw conclusions for the practical work completed on preparing standard solutions and titrating as
appropriate and relate the key features outlined in P1 to these conclusions. Learners must ensure the calculations for
the quantities in which chemicals react are accurate. The need for a safe working environment and risk assessments
should be reinforced by the tutor. The conclusions given by learners must be accurate and account for anomalous
results.
D1: Explain how standard solutions and titrations are prepared in industry
For D1, learners must relate their practical work in the laboratory to industrial applications and comment on how
procedures and equipment may differ in industry.
Task 1.1 – The Periodic Table of Elements (Part of P1)
Produce a leaflet, series of posters or a PowerPoint presentation outlining information on the Period
Table of Elements. Include the following:
 The basic structure of an atom
 What the notation in the boxes means (use the terms atomic number and relative atomic mass)
 Write out the number of protons, electrons and neutrons for the first 20 elements
 Explain how the electrons are arranged in shells and draw out the electron shell arrangement
of the first 20 elements
 How the electrons are arranged in orbitals (s, p, d, f) and write out the electron orbital
arrangement of the first 20 elements
 A copy of the periodic table with an explanation of how it is laid out and why (include terms like
group, period, metals, states).
 Choose 5 different elements and explain why each is in a particular group/period.
 Explain how the first ionisation energy of the elements changes when you cross a period and
cross a group
 Explain how the atomic radii of the elements changes as you cross a period and descend a
group.
