1st 2 2nd 8 3rd 18 4th 32 The highest energy level with any electrons in it
is called the outer shell. Using the Periodic Table Period Family http://studyjams.scholastic.com/studyjams/jams/science/matter/periodic-table.htm
Three Groups Metals Conduct heat and electricity well Becomes shiny when polished Melt at high
temperatures Can be easily reshaped Three Groups Nonmetals Have a dull surface Melt at lower temperatures Tend to break when
bent Three Groups Metalloids Have properties of both metals and nonmetals http://mrhardy.wikispaces.com/Periodic+Table.swf

http://www.wisc-online.com/objects/ViewObject.aspx?ID=SCI102 When one or more electrons from one atoms jumps to or is shared with another atom, a compound is formed. Sodium- shiny metal that catches fire when put in water and tarnishes quickly in air
Chlorine- a poisonous green gas http://studyjams.scholastic.com/studyjams/jams/science/matter/elements-and-compounds.ht m Formation of Sodium Chloride
https://www.youtube.com/watch?v=LK2fIn_U0MY Na+ Cl- Atoms with positive or negative charges are called ions.
Types of Bonds Ionic Bond - compound formed when an atom gives an electron to another atom Covalent Bond - when two or more atoms
share their electrons with each other https://www.youtube.com/watch?v=OdQqFHNOWAA&index=65&list=PLqTEqBBPoqwVTbS_6i2ls AmWTaW9312Fl Molecules A molecule is the smallest particle of

Temperature is a measurement of how hot or cold something is. It is a measure of how fast the particles in a material are moving. Solids Definite shape Particles move slowly
Particles packed tightly together http://www.kidsknowit.com/educational-songs/play-educational-song.php?song=Solid, Liqu id, Gas Liquids Definite
volume No definite shape Takes shape of its container Particles flow more easily than in solids
Gases No definite shape
No definite volume Particles flow freely Particles are spread far apart Solids, Liquids, and Gases http://studyjams.scholastic.com/studyjams/jams/science/matter/solids-liquids-gases.htm
Solids How tightly are the atoms packed together? How do the atoms
move? Examples Liquids Gases
Plasma Extremely hot Electrically charged Gaseous 99% of matter in the universe Rare on Earth Found mainly in
lightning https://www.youtube.com/watch?v=vDZhUkp30tE&index=107&list=PLqTEqBBPoqwVT bS_6i2lsAmWTaW9312Fl Melting Point- solid becomes a liquid (melting) Boiling Point liquid becomes a
gas (vaporization/evaporation) Freezing Point liquid becomes a solid (freezing) http://www.bbc.co.uk/schools/scienceclips/ages/8_9/solid_liquids.shtml Sublimation - occurs when a substance
changes directly from a solid to a gas Physical Changes A physical change changes the property of a substance without changing the substance completely. In other words, a physical change is reversible. http://studyjams.scholastic.com/studyjams/jams/science/matter/changes-of-matter.htm
Chemical Change Chemical changes cause a new substance to be formed, and they also either release energy or absorb it. Signs of a chemical change include: Smoking Change in color
Change in temperature Bubbling or fizzing http://glencoe.mcgraw-hill.com/sites/dl/free/0078600472/160350/00044680.html Mixture a physical combination of two or more substances that blend together without forming new substances. Homogenous Mixtures a
mixture that has the same uniform appearance and composition throughout. Heterogenous Mixtures - a mixture that contains distinct substances that are physically and often
visibly separate. http://studyjams.scholastic.com/studyjams/jams/science/matter/mixtures.htm Suspension a heterogeneous mixture made of parts that separate upon standing. Emulsion a suspension of two liquids that
usually do not mix together; rather, droplets are suspended Colloids a stable mixture in which small, fine particles of one material are scattered throughout another material blocking the passage of light and not settling out.

In the process of dissolving, the substance which is being dissolved is called a solute and the substance in which the solute is dissolved is called a solvent. solvent solute
A mixture of solute and solvent is called a solution. Factors that Affect Solubility: 1. Stirring 2. Crushing 3. Temperature
