  1. Minerals

  2. Minerals The earth is made up of matter, which consists of elements, which in turn consist of atoms

  3. 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

  4. Minerals What is an atom? The smallest particles of an element that retain all of its chemical properties

  5. Minerals

  6. Minerals Anion (-) Cation (+)

  7. Minerals

  8. 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

  9. Minerals What is a mineral? • naturally occurring • inorganic • crystalline solid • definite chemical composition • e.g. Quartz, SiO2

  10. Minerals There are nearly 4000 known minerals? How does one tell them apart? Physical Properties
