Periodic relationships, including, for example, atomic radii, ionization energies, electron affinities, and oxidation states.Electron energy levels: atomic spectra and atomic orbitals.Atomic number and mass number isotopes and mass spectroscopy.Atomic masses determination by chemical and physical means.

Structure of Matter (20%) Atomic theory and atomic structure The percentages next to the main topics indicate the approximate percentage of exam questions on that topic. The subject matter of the Chemistry exam is drawn from the following topics.

Interpretation: infer and deduce from data available and integrate information to form conclusions recognize unstated assumptions.Application: understand concepts and reformulate information into other equivalent terms apply knowledge to unfamiliar and/or practical situations use mathematics to solve chemistry problems.Recall: remember specific facts demonstrate straightforward knowledge of information and familiarity with terminology.Questions on the Chemistry exam require candidates to demonstrate one or more of the following abilities: Some of these are pretest questions that will not be scored. The exam contains approximately 75 questions to be answered in 90 minutes. To use the periodic table of elements during the exam, select the Help icon from the menu at the top of the screen and then select the Periodic Table tab. Students will find the online scientific calculator helpful in performing calculations (e.g., arithmetic, exponents, roots, and logarithms). Visit ETS to learn more and to practice using the scientific calculator. Students are expected to know how and when to make appropriate use of the calculator.

Scientific CalculatorĪ scientific (nongraphing) calculator, the TI-30XS MultiView™, is integrated into the exam software and available to students during the entire testing time. During this exam, an online scientific calculator function and a periodic table are available as part of the testing software. Understanding of the structure and states of matter, reaction types, equations and stoichiometry, equilibrium, kinetics, thermodynamics, and descriptive and experimental chemistry is required, as is the ability to interpret and apply this material to new and unfamiliar problems. The Chemistry exam covers material that is usually taught in a one-year college course in general chemistry.
