Matter
Anything have mass or volume
Mass
Amount of matter in an object
Weight
The pull of gravity on an object
Volume
The amount of space the matter occupies
Atom
Basic building block of matter
Monatomic atoms
Elements consisting of unbonded identical elements
Polyatomic elements
Several identical atoms bonded together
Hydrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodine, Nitrogen
Diatomic Elements
Allotropes
Different forms of an element in the same state of matter.
Elements
Samples of matter containing only one type of atom
Molecule
Any neutral group of bonded atoms
Compounds
Substances containing two or more types of atoms and have properties that differentiate themselves from their constituent elements.
Law of Definite Proportions
All samples of a given compound have the same composition by mass.
Vapor
The gaseous state of a substance that generally is found as a solid or liquid
Sublimation
Solid to gas
Condensation
Gas to liquid
Melting
Solid to liquid
Vaporization
Liquid to gas
Deposition
Gas to solid
Freezing
Liquid to solid
Pure Substances
Fixed composition and properties with a similar chemical formula
Mixtures
Containing two or more substances mixed together, not chemically bonded
Homogeneous Mixtures (Solutions)
Sample has the same composition and properties throughout, evenly mixed at the particle level.
Heterogeneous Mixtures
Different composition and properties in the same sample; unevenly mixed.
