4. Calculating Protons, Neutrons, and Electrons Atomic #: Protons and Electrons Atomic Mass: Neutrons and Protons Protons: Found at Atomic #: 26 Electrons: Found at Atomic #: 26 Neutrons: Found by subtracting protons from protons and neutrons, or Atomic #from Atomic mass.55.845-26= 29.845

5. Periods and Groups Periods Groups

7. Metals, Metalloids, and Non- Metals  Metals: Malleable and ductile, Good conductor of heat and electricity.  Non-Metals: Made up primary of gases, Not malleable or ductile, Cannot conduct heat or electricity.  Metalloids: Poor conductor of heat and electricity, Semi-conductor, Mixture of both metal and non-metal.

8. Elements, Compounds, and Mixtures

9. Chemical Reactions  Change in color -house hold chemicals mixing in lye.  Change in Temperature -hand warmers  Release of Gas -Blowing the balloon with baking soda and vinegar  Formation of a precipitate - Milk into stone  Release of Energy -helium balloon exploding by being exposed to fire.
