Structure of Atom — Class 11 ISC Chemistry revision notes
A 5-page visual revision sheet for Structure of Atom, written for Class 11 ISC Chemistry. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Structure of Atom sheet covers
- The three subatomic particles, and who found them
- Two models, and exactly what killed each
- Light, in the words used later
- Bohr's model, and the two postulates that carry it
- The hydrogen numbers worth knowing by heart
- radius of the nth orbit
- energy of the nth orbit
- velocity in the nth orbit
- spectral lines, Rydberg
- ionisation energy of hydrogen
- The hydrogen series, and where each one lands
- Why the model had to be replaced
- The quantum mechanical model in four numbers
- Capacity, subshell by subshell
- Filling the orbitals, three rules in order
- Writing a configuration without slips
- Photoelectric arithmetic, and the stopping potential
- Isoelectronic species, and the size order inside a set
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Chemistry chapter by chapter against your real exam dates and free hours, and when the plan reaches Structure of Atom the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
