THE COMPOSITION OF MATTER



Image from Science done wright. 
So, in summary:
  • element - a basic substance that can't be simplified (hydrogenoxygengold, etc...)
  • atom - the smallest amount of an element
  • molecule - two or more atoms that are chemically joined together (H2, O2, H2O, etc...)
  • compound - a molecule that contains more than one element (H2O, C6H12O6, etc...)
  • When you mix different substances (elements or compounds) you've got a mixture.
