Metals
Physical propeties
Ductile/Malleable
metal atoms same size, arranged in orderly layers. When force applied, layers can slide over one another
-
-
High mp/bp
strong metallic bond (between + metal ion & 'sea' of mobile electron), a lot of energy needed to overcome strong metallic bond
-
Alloys
-
Physical properties
Harder & stronger
Different sized atoms of another element, disrupt orderly arrangement of atoms, harder for atoms in alloy to slide over one another
-
-
-
Reactivity series
Please Stop Calling Me A Crazy (carbon) Zebra. I Like Hissing (hydrogen) Cobras So Go (further down, less reactive)
-
Metal + acid/steam (Please stop calling me, Zebra I)

-
Extraction of Iron
Raw materials
-
-
Limestone, calcium carbonate
-
-
-
Rusting
-
Speed up
Presence of NaCl, saltwater
-
-
Prevention
Protective layer, Acts as a barrier to prevent water and oxygen in air from coming into contact with iron surface
-
-
Recycling metals
-
-
-
-
-
more expensive as costs are needed to also collect, sort, separate, clean and transport old metal -
