Minerals The earth is made up of matter, which consists of elements, which in turn consist of atoms
Minerals What is an element? • a form of matter that cannot be broken down into a simpler form by heat, cold, or reaction with other chemical elements • there are 112 elements, 92 of which are naturally occurring
Minerals What is an atom? The smallest particles of an element that retain all of its chemical properties
Minerals Anion (-) Cation (+)
Minerals What causes ions to bond? They must be in close proximity for electrical attraction to exist. This can be done either by: a) cooling b) reduction in volume of solution
Minerals What is a mineral? • naturally occurring • inorganic • crystalline solid • definite chemical composition • e.g. Quartz, SiO2
Minerals There are nearly 4000 known minerals? How does one tell them apart? Physical Properties
