GCSE Chemistry: Simple Molecules

5th April 2017

GCSE Chemistry - revision at your fingertips

Simple molecules - what you need to know


Your GCSE exams are fast approaching so we are here to help you with your Chemistry revision. Understanding atoms, molecules and particles are a fundamental part of your studies, so let’s take a look at what simple molecules are to help you on your way to achieving great grades!


Simple molecules:

  • Contain only a few atoms

  • They are held together by covalent bonds

  • The covalent bonds are strong

  • The intermolecular forces are weak

  • Have low melting points - as a result of the weak intermolecular forces

  • Have low boiling points - as a result of the weak intermolecular forces

  • Have no free electrons - this means that they can not conduct electricity

  • Hydrogen is an example of a simple molecule

  • When a simple molecule boils or melts, the covalent bonds are not broken - it is  actually the intermolecular forces which break

  • The other covalently bonded substances are giant covalent structures - for more information about these have a listen to our song which deals specifically with this GCSE Chemistry topic

Now that you know the basic information related to simple molecules, take a listen to the song Simple Molecules and make sure to do the quiz to test your knowledge. For more songs on the GCSE Science topics, take a look to see what is available!
