Simulation Description: build Isotope, Atomic number and Mass number Isotope Builder — Simulation Students drag protons and neutrons into a nucleus. The element is identified live by proton count, and the isotope name (e.g. Carbon-14) updates instantly as neutrons are added. The same element with different neutron counts visually demonstrates what an isotope is. Class […]

Simulation Description: Atomic number and Mass number Mass Number & Atomic Number — Simulation Two sliders let students adjust protons (1–18) and neutrons (0–22). The screen updates instantly showing the element symbol and name on a periodic-table-style tile, the live equation A = Z + N, and a colour-split bar showing the proton/neutron ratio in

Simulation Description: Atomic structure – build an atom and ions with Protons, Neutrons and Electrons. What it does An interactive drag-and-drop atom builder covering AQA GCSE Physics and Chemistry. Students drag protons (red, +1), neutrons (blue, 0), and electrons (cyan, −1) from the bottom tray into a live animated atom. Protons and neutrons cluster in
