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!
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!
