Substances that are made up of only one type of atom OR of one type of compound
The particles in this substance tend to group together with like particles; making a substance that is NOT uniform in composition. This means that it is easy to see/distinguish that the substance is made up of multiple parts.
Made of 2 or more different types of atoms that are chemically bonded/combined in a fixed ratio and cannot be separated by physical means.
A substance entirely made up of only one type of atom
The parts of this type of substance are equally distributed (mixed up and spread out evenly) throughout, making a substance that appears to be completely uniform in composition (uniform = the same/one).
Two or more atoms that are chemically bonded/combined
(they can be the same type of atom or from different types of atoms; as long as there is MORE THAN ONE atom present)

ALL OF THESE ARE AN EXAMPLE OF THIS TERM
When two or more (different) pure substances are physically (not chemically) combined
The building blocks of matter. They are the smallest unit of an element that maintains the chemical properties of that element.
These types of substances are made up of more than one type of substance that CAN be separated or broken down by physical means (without breaking a chemical bond).
This is an example of a homogeneous mixture
