Elements = A substance that cannot be broken down into smaller substances
Atoms = smallest particle that has properties of an element
Compounds = a substance formed when two or more elements chemically combine together
Molecules = the smallest unit of a substance that exhibits all of the properties characteristic of that substance (compound)
- 2 + atoms chemically combines
Mixture = a physical combination of more than one substance
Homogeneous = Solution
-Same throughout the entire mixture
Ex: flat soda, salt water, black coffee
Heterogeneous = Not uniformly mixed, different parts
-Substances that need to be shaken
Ex: noodle soup, granites
