From the Outer Shell
Atomic structure knowledge mat for secondary schools (PDF)
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.

One purchase covers the school that buys it. Print it, copy it, hand it round your department. Not for passing to other schools or uploading anywhere.
One landscape A4 page on one topic, led by the figures and photographs rather than the headings. It carries how the atomic model changed, the particles and the scale of the atom, Mendeleev's gaps, Groups 1, 7 and 0 with shell notation, the four scientists and four predictions the table lets you make — then the vocabulary, a worked exam-style answer and the misconceptions that cost marks.
Every photograph on the sheet is a real archival or scientific image, not an illustration and not AI-generated; every diagram is drawn in code for the sheet. Each image was checked against its own licence template rather than a label, and the running foot names every creator, states that the images have been cropped and adjusted for print, and links the licence — so the sheet can be photocopied for a class and stay compliant. Every claim is sourced to the DfE subject content, and nothing is reproduced from a past paper, a textbook or a specification.
Sold by subject: all four chemistry sheets for one price. A knowledge organiser stores a unit and is revised from afterwards; this is meant to be on the table while the work is happening.
- Written to The DfE GCSE subject content for chemistry (DFE-00352-2014). Every photograph is a sourced archival or scientific image, licensed for reuse and credited on the sheet; every diagram is drawn in code for the sheet
- Intended for chemistry teachers — on the desk during the lesson, not a student revision guide
