Periodic Table / Chemical Reaction Notes
-7 Rows
called periods
each period represents the number of occupied energy levels in each element in the row
-18 Columns
called groups of families
shares similar chemical and physical properties
have the same amount of valence electrons

To the left of zig-zag line, metals. To the right, non-metals (gasses). Touching the line, metalloids (have both metals and metalloid properties).
Group 1: Alkali Metals
-Will lose only electron to become stable.
-Most reactive "metals"
Group 2: Alkali Earth metals
-Will lose two electrons in outer shell to become stable
Group 17: Halogens
-Will gain one electron to become stable
-Most reactive "non-metals"
Group 18: Noble Gases
-Most stable elements
-Outer shell full
-All found in the Earth's atmosphere
C2H4O2 + NaHCO3 --> H2O + NaO2C2H3 + CO2
_reactant_ + _reactant_ --> (yields) _product_
-A guy walks into a bar and orders H2O, and drinks it. Another guy comes in and says I want H2O too! (H2O2) and that guy falls over and dies.
