An element is a substance that consists of only one type of atom and cannot be broken down into simpler substances by chemical means
1 of 26
Properties of metallic elements
-good conductors of electricity and heat -solid at room temp except Mercury -usually have high melting and boiling points -usually maluble and ductile -shiny solids/lustrous
2 of 26
Properties of non metallic elements
Poor conductors of electricity and heat -tend to be soft and brittle -usually dull -low melting and boiling points
3 of 26
Malleable
Can be hammered into different shapes

Saturated solution
One which contains as much dissolved solute possible at that given temperature
23 of 26
Crystallistation
Occurs when crystals appear from a hot saturated solution which has been allowed to cool/ occurs when crystals appear from a solution which has been evaporated
