Document Summary
A particulate view of the world: structure determines properties (1. 1) Matter- anything that occupies space and has mass. Atom- a submicroscopic particle that constitutes the fundamental building block of ordinary matter; the smallest identifiable unit of an element. Molecule- two or more atoms joined chemically in a specific geometrical arrangement. Chemistry- the science that seeks to understand the properties of matter by studying the structure of the particles that compose matter. The structure of the particles that compose matter determines the properties of matter. Classifying matter based on the particles that compose it (1. 2) State- a classification of a form of matter as a solid, liquid, or gas. Composition- refers to the type of particles that compose matter; by composition is one way to classify matter. Solid- a state of matter in which atoms or molecules are packed close to one another in fixed locations with definite volume.
