Physics can get complicated at times and when it does, we use models to simplify things. The models aren’t wrong: in fact they work remarkably well, but they aren’t complete. Electricity provides probably the best examples of this state of affairs. Models normally start at the level of “electrons as buckets carrying energy” and include … Continue reading Electricity: models and theories
Atoms: Vital Statistics
In a previous article, I recapped the key facts you need to know about atoms. Here we will look at the numerical information you need to remember and the concept of isotopes. The table below lists the essental information you need to know about the three sub-atomic particles; protons, neutrons and electrons. There is an … Continue reading Atoms: Vital Statistics

Tucked away inside a website of astronomy resources I have just found a brilliant little tool for revising atomic structure, which is required knowledge for AQA Trilogy (and other) GCSE examinations in both physics and chemistry. You can find it at https://astro.unl.edu/newRTs/nuclei/. The assessment is a two-part, drag-and-drop ranking exercise where you have to rearrange … Continue reading Revising Atomic Structure
