Module 2 | Metals
Focus 2: Metals differ in their reactivity with other chemicals and this influences their uses
Lesson 1 | Reactivity of metals
-
Describe and justify the criteria used to place metals into an order of activity based on their ease of reaction with oxygen, water and dilute acids.
-
Describe observable changes when metals react with dilute acid, water and oxygen.
-
Construct word and balanced formulae equations for the reaction of metals with water, oxygen, dilute acid.
-
Perform a first-hand investigation incorporating information from secondary sources to determine the metal activity series.
-
Outline examples of the selection of metals for different purposes based on their reactivity, with a particular emphasis on current developments in the use of metals.
Lesson 2 | Metal reactivity and electron transfer
-
Identify the reaction of metals with acids as requiring the transfer of electrons.
-
Construct half-equations to represent the electron transfer reactions occurring when metals react with dilute hydrochloric and dilute sulfuric acids.
-
Identify the importance of first ionisation energy in determining the relative reactivity of metals.
-
Outline the relationship between the relative activities of metals and their positions on the Periodic Table.
