Learning Objectives

  • In this skill we will learn to classify particles as elements or compounds, and we will learn to classify substances as either pure substances or mixtures.
  • Elements contain only one type of atom.
  • Compounds contain atoms of more than one element that are chemically joined together.
  • A pure substance is made up of one type of particle only - either an element or a compound.
  • A mixture is made up of more than one type of particle - this could be a mixture of elements, a mixture of compounds, or a mixture of elements and compounds.
  • Homogenous mixtures are mixtures in which the different types of particles are evenly spread throughout.
  • Heterogenous mixtures are mixtures in which the different types of particles are not evenly spread throughout.

Tips

  • In these questions, different elements are shown by circles of different sizes and colors.
  • Elements can be monatomic (made up of just one atom) or diatomic (made up of two atoms chemically joined together).
