1. CLASSIFICATION OF MATTER

2. Pure Substances: Contain only 1 type of material Cannot be separated by physical means (filtration, etc.) Mixtures: Elements: Compounds: Homogeneous Mixtures: Heterogeneous Mixtures: Classifying Matter

3. Pure Substances: Contain only 1 type of material Cannot be separated by physical means (filtration, etc.) Mixtures: Made up of a variety of particles Can be separated using physical methods such as hand sorting, filtering, evaporation Elements: Compounds: Homogeneous Mixtures: Heterogeneous Mixtures: Classifying Matter

4. Pure Substances: Contain only 1 type of material Cannot be separated by physical means (filtration, etc.) Mixtures: Made up of a variety of particles Can be separated using physical methods such as hand sorting, filtering, evaporation Elements: The simplest forms of all matter Consist of only one type of particle called an atom. Only 117 elements Compounds: Homogeneous Mixtures: Heterogeneous Mixtures: Classifying Matter

Pure Substances: Contain only 1 type of material Cannot be separated by physical means (filtration, etc.) Mixtures: Made up of a variety of particles Can be separated using physical methods such as hand sorting, filtering, evaporation Elements: The simplest forms of all matter Consist of only one type of particle called an atom. Only 117 elements Compounds: Made of 2 or more elements chemically combined The particle is called a molecule The number of possible compounds is endless. Homogeneous Mixtures: Heterogeneous Mixtures: Classifying Matter

Homogeneous Mixtures: Also called solutions The particles are mixed together so completely that it looks like it is made of only one substance Heterogeneous Mixtures: Classifying Matter
