Self Assessment Checklist – The Periodic Table

Knowing the learning objectives is the first step in acing Chemistry. Master the essential concepts and apply them to interesting Chemistry questions confidently. Topical syllabus objective checklists are available here for your self-assessment. These checklists are based on Cambridge O-level Syllabus. Conduct self assessment when you revise. Tick against objectives that you can confidently say ‘I Can Do It’. Revise objectives that you are unsure of. Knowing what you need to know builds confidence in tackling questions. 

Work hard. Work smart. All the best.

Self Assessment Checklist - Periodic Trends

  I can do this!
aDescribe the Periodic Table as an arrangement of the elements in the order of increasing proton (atomic) number.
bDescribe how the position of an element in the Periodic Table is related to proton number and electronic structure.
cDescribe the relationship between group number and the ionic charge of an element.
dExplain the similarities between the elements in the same group of the Periodic Table in terms of their electronic structure.
eDescribe the change from metallic to non-metallic character from left to right across a period of the Period Table.
fDescribe the relationship between group number, number of valency electrons and metallic/non-metallic properties.
gPredict the properties of elements in Group I and Group VII using the Periodic Table.

Self Assessment Checklist - Group Trends

  I can do this!
aDescribe lithium, sodium and potassium in Group I (the alkali metals) as a collection of relatively soft, low density metals showing a trend in melting point and in their reaction with water.
bDescribe chlorine, bromine and iodine in Group VII (the halogens) as a collection of diatomic non-metals showing a trend in colour, state and their displacement reactions with solutions of other halide ions.
cDescribe the elements in Group 0 (the noble gases) as a collection of monatomic elements that are chemically unreactive and hence important in providing an inert atmosphere, e.g. argon and neon in light bulbs; helium in balloons; argon in the manufacture of steel.
dDescribe the lack of reactivity of the noble gases in terms of their electronic structures.

Self Assessment Checklist - Transition Elements

  I can do this!
aDescribe the transition elements as metals having high melting points, high density, variable oxidation state and forming coloured compounds.
bState that the elements and/or their compounds are often able to act as catalysts.
