NY Regents Chemistry study guide
NY Regents Chemistry · Work through your exam, one topic at a time.
The New York State Regents Examination in Chemistry - also called the Physical Setting/Chemistry Regents - is a New York State high school assessment in chemistry, administered by the New York State Education Department through its Office of State Assessment. It is intended for high school students who have completed a chemistry course aligned to New York State learning standards and who need the exam for a Regents diploma or as part of their science sequence. The NY Regents Chemistry study guide has 6 sections and about 2,179 words.
01Matter, Energy, and Measurement
This domain tests whether you can classify matter, separate mixtures, distinguish physical from chemical change, handle SI units and significant figures, and explain phase changes using kinetic molecular theory. Most items are short classification decisions or one-step calculations, so units and labels carry as many points as the arithmetic.
394 words, about 2 min02Atomic Concepts and the Periodic Table
This domain covers atomic models, subatomic particles, isotopes, electron configurations, and the periodic trends that let you predict radius, ionization energy, and electronegativity without memorizing every element. Protons (+) and neutrons (0) sit in the nucleus; electrons (−) occupy the space outside it.
387 words, about 2 min03Chemical Bonding and Intermolecular Forces
This domain tests why substances have the properties they do: bond type (ionic, covalent, metallic), molecular shape and polarity, and the intermolecular forces that set boiling point, vapor pressure, and solubility. Ionic bonding: a metal transfers electrons to a nonmetal.
358 words, about 2 min04Chemical Reactions and Stoichiometry
This domain checks whether you can classify and balance reactions, write net ionic equations, convert among mass, moles, and particles, and use mole ratios to find limiting reactants and percent yield. Synthesis: A + B → AB.
339 words, about 2 min05Kinetics, Equilibrium, and Thermodynamics
This domain links reaction rate, energy change, entropy, and reversible reactions. Expect questions on collision theory, potential energy diagrams, heat calculations, and Le Chatelier's principle.
334 words, about 2 min06Organic Chemistry and Nuclear Chemistry
This domain covers carbon compounds and nuclear change. You need the homologous series and functional groups, common organic reaction types, and balanced nuclear equations with half-life calculations.
