I. Classification of Matter
MATTER (anything that has mass & takes up space)

MATTER
PURE SUBSTANCE(matter with a
definite composition)Ex- water, helium, carbon dioxide,
sodium

MATTER
MIXTURE(2 or more pure
substances combined in ANY ratio)
Ex- lemonade, concrete, shaving cream
![Page 4: I. Classification of Matter](https://reader035.vdocuments.us/reader035/viewer/2022062811/568161ec550346895dd221df/html5/thumbnails/4.jpg)
Pure Substances
COMPOUND(2 or more elements chemically bonded
together)Ex- sodium chloride,
water, glucose, CLUE- chemical formulas have 2 capital letters; it is NOT on the periodic table
![Page 5: I. Classification of Matter](https://reader035.vdocuments.us/reader035/viewer/2022062811/568161ec550346895dd221df/html5/thumbnails/5.jpg)
Pure Substances
ELEMENT(cannot be broken down
any further)Ex- carbon, oxygen, lithium,
hydrogenCLUE- It is any substance
written on the periodic table
![Page 6: I. Classification of Matter](https://reader035.vdocuments.us/reader035/viewer/2022062811/568161ec550346895dd221df/html5/thumbnails/6.jpg)
Mixtures
SOLUTION(a homogeneous mixture
that cannot be filtered & will NEVER settle upon
standing)Ex- saline solution, grape
juiceCLUE- It is clear (might be
clear & colored)
![Page 7: I. Classification of Matter](https://reader035.vdocuments.us/reader035/viewer/2022062811/568161ec550346895dd221df/html5/thumbnails/7.jpg)
Mixtures
COLLOIDAL SUSPENSION(a homogeneous mixture
that cannot be filtered & will EVENTUALLY settle upon
standing)Ex- mayo, milk, fog, cool
whipCLUE- it creates the
Tyndall Effect

Mixtures
COURSE SUSPENSION(a heterogeneous mixture that can be filtered & will
QUICKLY settle upon standing)
Ex- Italian Dressing, OJCLUE- it has
distinguishable “pieces” in it.
