  • Elements are pure substance consisting of one type of atom 
  • Compounds are pure substances that can be separated into two or more elements 
  • Mixtures are substances mixed together but not combined (like a salad, you dont morph carrots and lettuce together you just throw them in alongside each other)

Suspensions are heterogeneous mixtures containing visible solid particles
