Size and Mass of Atoms | GCSE Chemistry (AQA)

In this Science revision video, we cover 'Size and mass of atoms and subatomic particles', a key component of the AQA GCSE Chemistry specification and exam, including the relative masses of the proton neutron and electron.

🔬 We cover the core concepts surrounding relative mass and charge of subatomic particles, inlcuding the significance of the atomic and mass numbers and how to work out the number of electrons, protons and neutrons from atoms or ions.

🧪 Including Quiz and examples tailored for GCSE students to help you revise and prepare for your exams.
