5 Minutes in Chemistry — Vol 1: Semester 1, Foundations to Bonding (22 Sheets)

Semester 1, one page per topic.

22 printable one-page sheets covering first-semester advanced-level high school chemistry and first-year college chem (Chem 101): matter & measurement, atomic structure, the periodic table & trends, ions & polyatomics, nomenclature, the mole, stoichiometry, limiting reactants, molarity, bonding, Lewis structures, VSEPR, polarity, IMFs, and gases.

Every sheet: one plain-English big idea · one signature chart · a "memorize this" box with every fact worth points · a 60-second self-test with hidden answers · the classic exam trap on that topic. Five minutes. Next topic.

Both US Letter and A4 included, built to print (even in black & white). Free updates — errata fixed in place, forever.
