Organizing Matter

Organizing MatterA. Several different methods – helps to

understand matterB. Based on physical and chemical observations

Organizing Matter - Mixtures

A. 2 or more parts of matter together

B. Each part keeps its own identity and characteristics

C. No chemical bonds form

D. May be easy to tell parts from each other or not

Organizing Matter - Heterogeneous

A. Not uniform in appearance – can see the different parts

B. Different parts spread out randomly, no organization

Organizing Matter - HomogeneousA. Uniform in appearance

– looks all the sameB. Parts are mixed evenly

and uniformly throughout , can’t tell one part from the other

C. Parts still have their own identity and characteristics

Organizing Matter - SolutionsA. Homogeneous mixtures

with very tiny particlesB. Solute – the part of the

mixture that dissolvesC. Solvent – causes the

solute to dissolveD. Solute and solvent do not

separate from each otherE. Solute and solvent keep

their own propertiesF. Do not bend light

Organizing Matter - ColloidsA. Heterogeneous mixtures B. Solute and solvent C. Solute particles are bigger

than those in solutions yet do not separate from the solvent particles

D. Solute particles are big enough to bend light (Tyndall effect)

Organizing Matter - Suspensions

A. Heterogeneous mixtures

B. Solute and solventC. Solute particles bigger

than colloid solutesD. Solute and solvent will

separate if not being stirred or mixed

E. Bend light

Organizing Matter – Pure Substances

ElementsA. Simplest form of matter;

cannot be broken down further

B. Each element is unique

CompoundsA. 2 or more elements

bonded together in a specific ratio

B. Compounds have different characteristics than their individual elements

A. Fixed compositionB. All parts of a pure substance have the same identity and characteristics

Other Organizations of MatterFor compoundsA. Organic: carbon based, carbon most importantB. Inorganic: no carbon, or carbon present but not most importantFor elementsC. Metal: good conductors of energy (esp. heat), malleable (forms

sheets/foils), ductile(forms wires), shiny, silver, gold, or copper in color

D. Nonmetal: good insulators (do not conduct energy), never malleable, never ductile, never shiny, can have color (but never silver, gold, or copper) or be colorless

E. Metalloid: some metal properties, some nonmetal properties
