Compounds and mixtures

• Use page 31 in your textbook to compare compounds and mixtures by completing the table on page 2 in your handout

• When finished: echalk: play tetris game to “identify elements, compounds and mixtures”

Elements, compounds and mixtures

Matter

Pure substances (fixed

properties)

Elements (one type of atom

only) (metals – nonmetals)

Compounds (two or more types of atoms chemically

combined)

Mixture (have properties of components)

Elements and compounds mixed together and not

chemically combined

definitions• Element

Substance made of one type of atom

• Compound Substance made of two or more different atoms

chemically combined

Compound and mixtureCompound Mixture

•Two or more different atoms chemically combined•Has fixed properties e.g. melting and boiling points, chemical reactions, ..•Has a fixed formula e.g. H2O•Can only be separated with a chemical reaction

•Two or more different atoms mixed together and not chemically combined•Has no fixed properties but the properties of those substances that are in it•Has no formula•Can easily be separated as components have not chemically combined
