Three-quarters of elements are metals. Characteristically metals are
shiny
good electrical conductors
ductile (shaped into wires)
malleable (hammered into sheets)
While the above properties are characteristic of metals, there is a considerable variation in these properties from metal to metal, and inevitably some metals are more suited to a particular use than others.
It is important,to take into account chemical reactivity of metals toward air and water when choosing a metal for a particular application . A more reactive metal may not be as suitable as a less reactive one.
This activity focuses on the metals that are highlighted in the periodic table on this page.

Those which are common in everyday life include
iron (Fe) used in roofing and mixed with other metals in steel
aluminium (Al) used for cooking foil
lead (Pb) used in car batteries
copper (Cu) used in electrical wiring
zinc (Zn) used in galvanising to protect iron from corrosion
magnesium (Mg) used as a mixture with other metals where a light weight metal is required
Two of these metals that are too reactive for most applications are
sodium (Na). This metal is very soft and low melting.
calcium (Ca). This metal is brittle.
