MATTER SYSTEMSVersion en ligne GROUP THE CHARACTERISTICS OF THE DIFFERENT TYPES OF MATTER SYSTEMS. par Hermelinda Pujol Yánez 1 HETEROGENEOUS MIXTURES 2 HOMOGENEOUS MIXTURES 3 COLLOIDS 4 COMPOUNDS 5 ELEMENTS or SIMPLE SUBSTANCES Their components can be distinguished with the naked eye Their properties and composition vary from one part to another of the same sample Some examples are granite, sand or wood. Their components cannot be distinguished with the naked eye neither with a microscope Their properties and composition are the same in any part of the sample. They are also called solutions Some examples are: saltwater, bronze or alcohol 96º Their components cannot be distinguished with the naked eye but with a microscope There are two phases: a dispersed phase and a dispersion medium They can cause light scattering (Tyndall effect) Some examples are: milk, blood, or smoke They can be separated into simpler substances by chemical methods, such as electrolysis or thermal decomposition Some expamples are: water (H2O). glucose (C6H12O6) or salt (NaCl) They are pure substances made of atoms of different elements They are made of the same type of atoms They cannot be separated into simpler substances. There are 118 in the Periodic Table. Some examples are iron (Fe), hydrogen (H2) or carbon (C)
