Chapter 1Section 2 Matter and Its PropertiesBasic Building Blocks of Matter An atom is the smallest unit of an element thatmaintains the chemical identity of that element. An element is a pure substance that cannot bebroken down into simpler, stable substances and ismade of one type of atom. A compound is a substance that can be broken downinto simple stable substances. Each compound ismade from the atoms of two or more elements thatare chemically bonded.

Chapter 1Section 2 Matter and Its PropertiesPhysical Properties and Physical Changes,continued A change of state is a physical change of asubstance from one state to another. states of matter—solid state, liquid state, gas state,plasma In the solid state, matter has definite volume anddefinite shape. In the liquid state, matter has a definite volume butan indefinite shape.

Chapter 1Section 2 Matter and Its PropertiesClassification of Matter A mixture is a blend of two or more kinds of matter,each of which retains its own identity and properties. mixed together physically can usually be separated Homogeneous mixtures are called solutions uniform in composition (salt-water solution) Heterogeneous mixtures not uniform throughout (clay-water mixture)
Chapter 1Section 2 Matter and Its PropertiesTypes of Mixtures
Chapter 1Section 2 Matter and Its PropertiesPure Substances A pure substance has a fixed composition. Pure substances are either compounds or elements. A pure substance differs from a mixture in thefollowing ways: Every sample of a given pure substance has exactly thesame characteristic properties. Every sample of a given pure substance has exactly thesame composition. Water is always 11.2% hydrogen and 88.8% oxygen bymass.
