7. Element and Compound Element - cannot be separated into simpler substances –Example: mercury –Can see on the periodic table Compound – atoms of different elements chemically combined –Example: mercury sulfide –Must be chemically taken apart You will learn the classification of matter.

8. Matter Concept Map Continued Mixture HomogeneousHeterogeneous You will learn the classification of matter.

9. Homogeneous and heterogeneous Homogeneous: the same throughout –Example: stainless steel Heterogeneous: not the same throughout –Example: granite You will learn the classification of matter.

10. Separation Techniques Distillation –separation process –water is boiled off, changed to steam, and leaves a precipitate. –steam is collected & cooled, condensing to pure water. Electrolysis –using an electric current to drive a non- spontaneous chemical reaction –can be used to separate compounds. You will learn separation techniques.

11. Cont. Filtration –Separates a liquid from a solid –Liquid passes through filter paper and solid remains You will learn separation techniques.
