Atoms & Elements
Anything that has mass and takes up space
Matter
The force that holds two atoms together
Bond
Matter that has a constant chemical composition and characteristics
Substance
Definite shape and definite volume; particles vibrate in place; particles have the least amount of kinetic energy
Solid
Solid --> Liquid
Melting
An individual particle of matter
Atom
A group of atoms bonded together
Molecule
The amount of matter in an object
Mass
Indefinite shape and indefinite volume; particles spread out; particles have the most amount of kinetic energy
Gas
Gas --> Liquid
Condensation
A table that lists all of the known elements and groups them into columns by property.
Periodic table
The molecule that gets repeated in an extended structure
Polymer
The ability of a substance to dissolve into another substance
Solubility
Indefinite shape and definite volume; particles slide around each other; particles have a medium amount of kinetic energy
Liquid
Liquid --> Gas
Boiling
What Mendeleev used to arrange elements into the periodic table
Properties
When atoms are arranged in a repeating, three-dimensional pattern
Crystal
A property that can only be determined by making a substance undergo a chemical reaction
Chemical property
The point in which a substance changes from a liquid to a gas
Boiling point
Gas --> Solid
Deposition
This number increases as you go down and to the right on the periodic table
Atomic mass
The specific way atoms are arranged in a molecule
Atomic structure
Density formula
Density = Mass / Volume
Particles move because they have this type of energy
Kinetic energy
Solid --> Gas
Sublimation
