AP Chemistry has been recently revised by College Board. The following table reflects the organization of the curricular elements from large (big ideas) to more specific (learning outcomes).
The table below is summarized from
Any errors arising from my re-phrasing, oversimplification are solely mine. The original document is better. - CPK.
| Big Idea | Enduring Understanding | Learning objective | Essential Knowledge | |
| 1) Scale, proportion, quantity: Explanations and predictions in Chemistry require working across scales ranging from sub-atomic to macroscopic. (SPQ) | SPQ1 The mole allows different units to be compared. | SPQ 1.A Calculate quantities of a substance, or number of particles using dimensional analysis and the mole. | SPQ1.A.1 Atoms and molecules cannot be counted directly, therefore they must be converted to mass using the mole | |
| SPQ1.A.2 Avogadro's number 6.022E23 particles/mole provides the connection between mass and number of particles. | ||||
| SPQ1.A.3 The mass of 1 mole of substance is the sum of the average atomic masses of its constituents. Molar Mass | ||||

| SAP 1 Atoms and molecules can be identified by their electron distribution and energy. | SAP 1.A Represent the electron configuration of an element or ion using the Aufbau Principle | SAP 1.A.1 The atom is made of negatively charged electrons and a positively charged nucleus. The nucleus is made of protons and neutrons. | ||
| SAP 1.A.2 Coulomb's Law is used to calculate the Force between two charged particles. F = K Q1Q2/r2 | ||||
