Chemistry KS4: GCSE Periodic Table of Elements


Curriculum Support


20 mins


Host: Jamie Johnson - BSc (Hons), MSc, PGCE. Jamie is a Science teacher who is passionate about breaking down complex topics into digestible bites for students. 

The modern periodic table is one of the most important pieces of work in chemistry, and adorns every science classroom.

All UK pupils study it for high school science, but many do not understand the steps taken to develop the table in its current form.

This lesson covers the steps involved in the discovery and development of key ideas that led to it.

Safeguarding reminder:  We know that the safety of your child is of the utmost important. This is why we use Zoom's Webinar feature to provide our live classes, where by default, your child's webcam and microphone are disabled. 

Key takeaways:

  • Describe how Mendeleev arranged the elements known at the time into the periodic table, using prior ideas.
  • Describe how Mendeleev predicted the position and properties of unknown elements, and the problems in his approach.
  • Explain the discovery by Moseley around atomic number that helped confirm Mendeleev’s ideas.

Suitable for:

This class is suitable for all ages, especially for students looking to revise a key concept in
science in Years 10 and 11.
