Substances that are made up of only one type of atom OR of one type of compound (they are the same substance throughout).
The particles in this substance tend to group together with like particles (the same type of atom/compounds); 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 of the same OR different types of atom chemically bonded/combined. It doesn't matter if the atoms are all the same element or different elements; just that there are multiple atoms bonded together
When two or more (different) pure substances are physically (not chemically) combined and exist in the same space, it is called a ________.
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).
All PURE substances can be broken down into simpler substances by physical means
All compounds are molecules but not all molecules are compounds.
