Mijo's Flashcards

Describing atoms, molecules, and matter

Atoms They are things made up of a nucleus, protons, and neutrons
Molecules They are a bundle of specific types of atoms put together to form this.
Matter This is made up of molecules and atoms; they also take up space and have mass.
Elements is when one or more atoms of the same kind are bonded together.
Compounds are when two or more different atoms get bonded together.
Pure Substance Is a substance that is made up of one type of atom and can not be separated using physical means (must be chemically separated).
Mixture A substance made up of multiple types of matter and has a variable composition, this mixture can be separated using physical means.
Homogeneous Mixture A mixture where the particles are evenly distributed are also considered solutions
Heterogeneous Mixture A mixture where the particles are not evenly distributed throughout the mixture.
Solution A mixture containing atoms, ions, or molecules fully dissolved
Colloid A mixture containing mid-size particles that do not settle out
Suspension A mixture containing particles that settle out if left undisturbed
Tyndall Effect dispersed colloid particles scatter light, allowing us to differentiate between colloids and solutions
