Chapter 1: Atoms 1.1 A Particulate View of the World: Structure Determines Properties  matter is particulate/composed of particles  structure of those particles determines the properties of matter  matter: anything that occupies space and has mass  atoms: basic particles that compose ordinary matter o smaller particles than matter  molecules: atoms that bind together in a specific geometrical arrangement  water molecules = really small and structure determines its properties o water is bent => if it’s linear, it’d have a lower boiling point; weakened attraction b/t molecules; easier to evaporate; solutes won’t dissolve as easily **change in structure = change in function and properties  chemistry: science that seeks to understand the properties of matter 1.2 Classifying Matter: A Particulate View  substance: a specific instance of matter (Ex: air, water or sand)  state of matter: first classification (of matter) depends on relative positions of the particles and how strongly they interact with one another relative to temperature  composition of matter: second classification that depends on the types of particles The States of Matter: Solid, Liquid, and Gas  solids: matter that attracts to one another strongly and pack close to each other o has fixed volume and rigid shape  liquids: matter that packs as close as particles in solid matter but w/ slightly weaker attractions o has fixed volume but not fixed s
