Document Summary

1. 1 a particulate view of the world: structure determines properties. The structure of the particles determines the properties of. Matter is anything that occupies space and has mass. Atoms are basic particles that compose ordinary matter. Close to 91 different types of atoms exist naturally. Molecules are atoms bonded together in specific geometrical arrangements. The properties of substances depend on the structure of the molec. Of particles composing a substance results in a significant change in the properties of the substance. Chemistry is the science that seeks to understand the properties. A specific instance of matter--such as air, water, or fire--is a substance. We classify matter based on the particles composing it. The first classification is the state of matter which depends on the relative positions of the particles and how strongly they interact with one another (relative to temp. )
