The Classification of Matter

The Classification of Matter

Pure Substances (All particles are identical and can be chemically separated) Elements made of only one type of particle Metals found on the left side of the periodic table (e.g. gold - Au) Non-metals found on the right side of the periodic table (e.g. oxygen - O) Metalloids have properties of both metals and non-metals (e.g. silicon - Si)

Pure Substances Compounds made of two or more types of particles Inorganic (non-living) Ionic (metal + non-metal elements) e.g. salt (NaCl) Polyatomic (3 or more elements) e.g. chalk (CaCO3) Covalent/Molecular(2 non-metal elements) e.g. water (H2O) Organic (living)

Mixtures (Contains different particles mixed together that can be physically separated) Homogenous one visible phase in either a liquid solution or a solid metal alloy e.g. koolaid or brass Heterogenous two or more visible phases involving solids or a liquid colloids e.g. sand or milk
