The invisible architecture of matter: atoms, isotopes, and energy levels
In short: This video breaks down the fundamental building blocks of matter for the 2027/28 GCSE Physics exams. It explains how subatomic particles organize into atoms and how electrons move between energy levels to create radiation.
The video covers the core components of an atom: protons, neutrons, and electrons, detailing their relative masses and charges. It explains how to read nuclear symbols, specifically distinguishing between the atomic number (the number of protons) and the mass number (the sum of protons and neutrons).
A key focus is the concept of isotopes—atoms of the same element with different neutron counts—and the conditions that lead to radioactive decay in unstable isotopes. Additionally, the content explores electron behavior, including how atoms become positive ions through electron loss and how electrons emit electromagnetic radiation when falling from higher to lower energy levels.
