The Chemistry Glossary lists more than 500 terms from New York State Chemistry: the vocabulary of the Chemistry learning standards (NYSSLS performance expectations) and of released Chemistry Regents exam questions, along with the substances, elements and units they name.

This glossary is strictly limited to terms originating from official NYSED materials such as standards and released test questions. Every term links to its source: a performance expectation (for example HS-PS1-5) means the term appears in that standard's text, clarification statement, assessment boundary, disciplinary core ideas or performance level descriptions; an exam cluster means the term appeared in that released question cluster, and the link opens the question. Sections: vocabulary from the standards, vocabulary from released exams, substances, ions and materials, elements, units, and terms the standards point to without naming.

Vocabulary from the standards

Terms used in the chemistry performance expectations and their supporting NYSED text. This is the core vocabulary; the science-practice and engineering words the standards use (claim, evidence, criteria, trade-off) are included because the exams use them the same way.

Vocabulary from released exams

Terms that do not appear in the standards' text but have appeared in a released Regents question cluster. The exam is noted after each term; the link opens the question.

Substances, ions and materials

Specific chemicals, ions and materials that the standards or exam clusters name, grouped by source so teachers can see the kinds of substances NYSED writes about. An entry marked "formula only" was printed as a formula but never named in words.

From the standards

Spring 2025 sample clusters

August 2026 exam

June 2026 exam

Elements

Elements named in the standards or exam clusters (43). The link opens the standard or question; an element that appears only as a symbol in an equation or answer choice is linked to that question too.

Units

Units used in the released exams. Parts per million and STP are listed under vocabulary from the standards.

Implied terms

These terms are not named in the standards or released exams, but the NYSED wording points to them so directly that teachers will want to use them. Each entry quotes the wording that implies it. Terms that could be argued either way are deliberately left out; in particular, hydrogen bonding and London dispersion forces are not listed because HS-PS1-3 says the emphasis is "not on naming specific intermolecular forces," and Charles’s and Gay-Lussac’s laws are not listed because HS-PS1-9 assesses "the relationships among the variables of the combined gas law, not the gas law names."
