  • elements are made up of tiny particles called an atom 
  • all atoms in given element are identical 
  • the atom of a given element  are different from those of any other element .
  • atoms of other elements can combine with other elements to form compounds
  • in chemical reactions atoms are neither destroyed or created  they change the way they are grouped together.
