Kinds of Matter All matter is made up of either pure substances or mixtures of pure substances

All Matter Pure Substances Mixtures Compounds Elements

Elements Simplest form of matter (nothing simpler) Building blocks that make up every different variety of matter in the universe

My Periodic Table Yes I still have it, and you will get one too!

All Matter Pure Substances Mixtures Compounds Elements

Compounds A pure substance made up of elements that are chemically combined in a specific ratio Perfectly homogenous (same throughout) Has a definite composition regardless of its origin, location, size, or shape Can be decomposed to the elements that make it up only through a chemical change

NaCl H2O Compounds Much more abundant than elements alone Ex: Water, sugar, salt, hydrogen peroxide NaCl H2O

Compounds When elements combine to form a compound, the elements lose all of their properties, and a new set of properties unique to the compound is created NaCl

All Matter Pure Substances Mixtures Compounds Elements

Mixtures When 2 or more substances combine yet retain their individual properties Held together by physical means Thus, separated by physical means Filtration, absorption Ex: soil, most rock, plants, animals, coal, air, rivers

Mixtures Can be 2 Types Homogeneous Heterogeneous Have the same composition throughout Ex: dissolving sugar in water -called a solution Solution almost always with water because only liquid found in nature Composition is not the same, or uniform , throughout Ex: mineral -you can see the differences in composition from spot to spot within the mineral sample

Homogeneous Mixtures are Solutions Solute Solvent Dissolved substance Ex: Sugar The dissolving agent Ex: Water All solutions consist of one or more solutes and a solvent
