How to draw a Bohr diagram 4 steps · use the arrow keys or the buttons What do the numbers mean? Tap the symbol · change the particles How ions form 5 steps · you move the electron Lewis diagram guide 3 steps · use the arrow keys or the buttons Metals and acid 4 steps · you test each metal The first 20 elements, in the table Tap an element · see why it sits there Down the group Pick a group · step down it one element at a time Read a formula Tap a number or a symbol to see what it counts Balance an equation 3 steps · change only the big numbers Particles and heating One slider · the particles stay the same Collisions and rate Change one factor, press Run, compare the lines

Sixty-second drills

Fluency against a clock. Scored apart from quizzes, on purpose — fast recall is not the same thing as understanding.

Read the tile Protons, neutrons, mass, symbol, group. Find it on the table Click the element it asks for. Put it in its place Drag a tile onto a blank grid. Atom challenge Build the atom, or name it from its shells. No clock. Build an atom The sandbox. No clock, no score, nothing saved.

Targeted concept & lab quizzes

Interactive smart quizzes on core curriculum topics and practical labs, ready to play or assign.

Bohr model quiz Build atoms, ions and isotopes up to calcium with the interactive builder. Electron arrangement Shell capacities (2, 8, 8), outer-shell electrons and writing arrangements. Lewis diagrams Place valence dots, draw ion brackets, and show electron transfer. Periodic Table Groups, periods, outer-shell patterns and family trends. Balancing equations Interactive balancer tool: balance coefficients and count atoms. Lab 1: Alkali metals Reactions of Li, Na and K in water, equations, indicators and why reactivity rises down the group. Lab 2: Burning magnesium Crucible method, mass calculations and conservation of mass. Lab 3: The copper cycle The 3 stages: oxidation, acid-base, displacement and atom conservation.
