Old test and earlier [ edit ] The old test was composed of two sections: Section I, the multiple-choice portion, did not allow the use of a calculatornor did it provide any additional reference material, other than a periodic table.
Each question contained five answer choices. Section I covered the breadth of the curriculum. Section II, the free response section, was divided into two sections: Part A, requiring the completion of three problems, and Part B, also containing three problems. Part A, lasting 55 minutes, allowed the use of calculators, while Part B, lasting 40 minutes, did not.
The first question of Part B was a chemical equation question in which 3 scenarios were presented and the student was required to work all 3 scenarios, authoring a balanced net ionic chemical equation for each scenario and answering questions about the equations and scenarios.
If time permitted, students may have edited their responses from Part A during the time allotted for responding to Part B, though without the use of a calculator.
The student needed to have completed all six questions. While the use of calculators was prohibited during Section I and Section II Part B, a periodic table, a list of selected standard reduction potentials, and two pages of equations and conventions are available for use during the entirety of Section II.
New test and later [ edit ] This section needs expansion. You can help by adding to it.
February The AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the past years, with 60 multiple choice questions now with only four answer choices per question3 long free response questions, and 4 short free response questions.
The new exam has a focus on longer, more in depth, lab-based questions. The penalty for incorrect answers on the multiple choice section was also removed.

First, recall that the electron, being a quantum particle, cannot have a distinct location; the most we can do is define the region of space around the nucleus in which the probability of finding the electron exceeds some arbitrary value, such as 90% or 99%.
