This comprehensive guide compiles essential chemistry concepts, definitions, and chemical formulas. It is designed to help you revise quickly and maximize your score. 1. Matter and Its Composition He wrote quickly, accurately, and with understanding
Increases across a period. Decreases down a group.
Exams love exceptions, such as liquid non-metals (Bromine) or metals that can be cut with a knife (Sodium).
He fought the mole concept. Every time he wrote "Avogadro's number = 6.022 x 10^23," he imagined a giant mole digging through a tunnel of atoms. For "Raoult's Law," he sketched a crying vapor pressure man. His notes were ugly, but they were his . Pure substances containing only one type of atom (e
