Bought once for the set, not per sheet. Photocopy them for your classes freely — keep the running foot on the page, which carries the image credits the licences require. One purchase covers the school that buys it. Downloading it ends the 14-day right to cancel; a file that is faulty or not as described is always refunded. Refunds
Why an element’s place in the table tells you how it will react, and why Mendeleev’s gaps turned out to be right. Six dates on how the model of the atom changed, from Dalton to Chadwick; the particles and the scale of the atom; Mendeleev’s own first table; Groups 1, 7 and 0 with 2,8,1 shell notation; the four scientists a GCSE answer needs; four things the table lets you predict. Eight terms to define, a model answer on why the group trends run opposite ways, and the misconceptions that cost marks.
Why something held together by strong covalent bonds melts in your hand while a salt needs 800 °C. Ionic, covalent and metallic bonding; carbon three ways as diamond, graphite and graphene, with the bond count that decides everything; the three states and the particle model’s own limitations; diamond, buckminsterfullerene and gold nanoparticles compared; a worked surface-area-to-volume ratio. Ten terms to define, a model answer contrasting chlorine and sodium chloride, and the misconceptions that cost marks.
Why a dilute strong acid is not the same as a concentrated weak one, and how you know what appears at each electrode. Acids, alkalis and pH drawn against hydrogen-ion concentration; the reactivity series in full, with carbon and hydrogen placed in it; electrolysis of melts and solutions; four gas tests and the observation that earns the mark; balancing an equation the way that always works, state symbols included. Ten terms to define, a model answer on strong versus concentrated, and the misconceptions that cost marks.
What actually changes when a reaction speeds up, and why a catalyst gets you there sooner but never further. Collision theory and a rate graph read by its gradient; exothermic and endothermic profiles side by side with activation energy marked; chemical and fuel cells, with the Space Shuttle’s fuel cell photographed; the three levers that shift an equilibrium and the one that does nothing; a worked bond-energy calculation. Eight terms to define, a model answer on temperature and rate, and the misconceptions that cost marks.
The previews above are the full sheets, watermarked. Where a sheet carries photographs, every one is public domain worldwide or licensed CC BY, verified per image against the licence itself rather than a label, and the running foot names every creator, records that the images have been cropped and adjusted for print, and links the licence; figures are drawn in code for the sheet, and extracts are written for it or verified against a public-domain text. Nothing on any sheet is reproduced from a past paper, a mark scheme, an examiner report or a specification, and Empower Educators is not affiliated with any awarding body.
