10
Atom: The smallest part of an element that has its same chemical composition
Heterogenous Mixture: A mixture where you can see the different parts and it is physically combined
Element: Pure substance that cannot be separated into simpler substance by physical or chemical means
Homogenous Mixture: A mixture that is uniform throughout and you cannot see the different parts
Mixture: A combination of two or more pure substances that are not chemically combined
Compound: A combination of two or more elements that are chemically combined. Ex. NaCl
Chemistry: The study of matter, atoms, electrons and the interactions between them
Sublimation: Matter that changes directly from a solid to a gas. Ex. Dry ice
Molecules: combination of two or more atoms, Some are made of atoms that are all alike, like oxygen
Matter: What everything in the world is made up of. There are technically 5 states but the most common are solids, liquids, and gases
