Matter- Anything that has a mass and a volume
States of Matter
Solid
Liquid
Gas
Plasma
•
Changing from one state to another is a Physical Change.
•
If a new substance is formed it is a Chemical Change.
Atoms
•
•
The building blocks of Matter
Consists of Protons (+), Electrons (-), and Neutrons (N).
Elements
•
Consists of only one kind of atom,
•
Cannot be broken down into a simpler type of matter by either physical or chemical means
•
Can exist as either atoms or molecules.
Molecules
•
A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.
Compounds
•
Atoms of two or more different elements bound together.
•
Can be separated into elements chemically, but not physically.
Solutions
•
Solutions are groups of molecules that are mixed up in a completely even distribution.
Homogeneous
•
•
Solute
•
Uniform Distribution.
Example: Sugar and Water
The substance to be dissolved.
Solvent
The one doing the dissolving
Solute + Solvent= Solution
Colloids
•
Particle sizes are in between the size of particles found in solutions and suspensions .
•
Can be mixed and remain evenly distributed without settling out
Mixtures
•
They are substances held together by physical forces, not chemical.
•
Can be separated physically.
•
Solutions are also mixtures.
Heterogeneous
•
The substances are not uniformly mixed.
•
Example: Sand in a glass of water.
Suspensions
•
Are heterogeneous mixtures consisting of parts that are visible to the naked eye.
