metals and non metals

• left side of the periodic table consists of metals
• properties of metals: good conductors of heat and electricity, ductile (can be stretched into wires), malleable (beaten into different shapes), strong and lustrous (shiny)
• properties of non-metals: not good conductors (good insulators), brittle (shatter when beaten), weak and dull
• alloy: a mixture of metals
• brass: copper and iron
• rusting: a chemical reaction in which iron is changed into rust
• rusting requires water, oxygen and metal to occur
• painting, oiling and galvanising are the best ways to prevent rusting
