Science 1.7 Investigate the implications of the properties of metals for their use in society
Subject content
- The actual metals you are required to work with will be decided by your school but will include a good range of properties
- You will need to know the names and symbols of the metals you use
- Physical properties you need to be able to describe and compare/contrast include melting point, colour, lustre, hardness, malleability and ductility, electrical and thermal (heat) conductivity and density(how much each cubic centimeter of metal weighs)
- The products when the metals react (if they do) with oxygen, water and the acids HCl and H2SO4 must be known
- Uses of the metals chosen and how these uses are connected to the chemical and physical properties of each metal
- Ways of preventing corrosion of each metal and how the properties of the metal influence the method and extent of protection needed
- Ways in which metals are extracted from their ores and how the method used is influenced by the properties of each metal
- How to apply an activity series of metals when discussing chemical reactions (including corrosion), uses and extraction from ores
- How to write word and balanced symbol equations for the reactions studied.
