slide2
Matter
  • Anything that has a mass and a volume
slide3
States of Matter

Solid

Liquid

Gas

Plasma

Close up view of atoms and their behavior

slide4
Physical vs. Chemical Change
  • Changing from one state to another is a
  • Physical Change.
  • If a new substance is formed it is a
  • Chemical Change.

slide5
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.

Images are from http://www.chem4kids.com

slide6
Molecules
  • A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.
  • In the animation above, two nitrogen atoms
  • (N + N = N2) make one Nitrogen molecule .
slide7
Compounds
  • Atoms of two or more different elements bound together.
  • Can be separated into elements chemically, but not physically.

In the animation above, water (H20) is a compound made of Hydrogen and Oxygen.

slide8
Solutions
  • Solutions are groups of molecules that are mixed up in a completely even distribution.

Homogeneous

  • Uniform Distribution.
  • Example: Sugar and Water

slide9
Solute
  • The substance to be dissolved.

Solvent

  • The one doing the dissolving.

Images are from http://www.chem4kids.com

slide11
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.
slide12
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.

Images are from http://www.chem4kids.com

slide13
Mixtures

Suspensions

  • Are heterogeneous mixtures consisting of parts
  • that are visible to the naked eye.
  • Substances will settle over time.

Example: the ingredients in salad dressing
