The Periodic Table (Topic: 8 Section: 8.1, 8.2 & 8.3)
(a) describe the Periodic Table as an arrangement of the elements in the order of increasing proton
(atomic) number
(b) *describe how the position of an element in the Periodic Table is related to proton number and
electronic structure
(c) *describe the relationship between group number and the ionic charge of an element
(d) explain the similarities between the elements in the same group of the Periodic Table in terms of
their electronic confi guration
(e) describe the change from metallic to non-metallic character from left to right across a period of the
Periodic Table
(f) *describe the relationship between group number, number of valency electrons and metallic/
non-metallic character
(g) *predict the properties of elements in Group I, VII and the transition elements using the Periodic
Table
(a) describe 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
(b) describe 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
(c) describe the elements in Group VIII (the noble gases, also known as Group 0) 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
(d) describe the lack of reactivity of the noble gases in terms of their electronic structures
(a) describe the central block of elements (transition metals) as metals having high melting points, high
density, variable oxidation state and forming coloured compounds
(b) state the use of these elements and/or their compounds as catalysts, e.g. iron in the Haber process;
vanadium(V) oxide in the contact process; nickel in the hydrogenation of alkenes, and how catalysts
are used in industry to
