Chemistry KS4: Atomic Structure of Elements

Curriculum Support

On Demand

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.

It lists all the known elements, but what makes each element unique?

Scientists know about the structure of the element atoms, and this is now expected knowledge for all GCSE chemistry students. It would be impossible to simply memorise them, but the periodic table is a useful tool that lets us calculate what we need to know using a few simple rules.

This lesson covers the steps involved in the determination of the number of each subatomic particle present in each element atom, as well as their arrangement.

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 the general atomic structure, using the subatomic particles and their characteristics.
  • Describe how to calculate the number of subatomic particles per element atom using information from the periodic table, with examples.
  • Explain how to determine the electronic structure of an atom using the periodic table.

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.

Class requirements

A laptop and internet connection are required for this class.

Also, access to a periodic table (can be found online or in any GCSE science textbook), a calculator, pen and paper to make notes are required.
