6.2 Making up a solution on known concentration (standard solution)... Theory + Prac bonus

Ok in this video we are looking at the basic structure of atoms. In junior school you learnt the following structure:

This is an ok model as it describes atoms being made up of 3 subatomic particles:

  • protons (positive charge) and located in the nucleus
  • neutrons (neutral in charge) and located in the nucleus
  • electrons (negative in charge) and located outside the nucleus in regions we call electron shells.

This model is a good start, but has its limitations. We will start with this and extend it in the next few videos.

Let's get into it.
