Atomic structure is the foundation of GCSE Chemistry — and one of the most common reasons students lose easy marks across the exam.
In this episode of STEM’Learn, we break down atomic structure in a clear, examiner-focused way. You will learn how examiners expect you to describe atoms, particles, and electron arrangements — and where students most often make mistakes.
We cover:
– the nucleus and electron shells
– protons, neutrons, and electrons (location and charge)
– atomic number vs mass number
– how to calculate the number of neutrons
– electron shells and the 2,8,8 rule at GCSE level
– the examiner language that secures marks
This episode is designed as calm, structured revision for GCSE students, especially international and non-native English speakers.
Atomic structure is not just one topic — it underpins bonding, the periodic table, and high-mark questions throughout the exam.
