Day 7 notes

• Record the following notes on page 6 of your
  foldable
• How to determine oxidation numbers
• Find the group number (roman numeral) for the
  element (located at the top of the group).
• Determine if the element is a metal or a
  nonmetal.
• If it is a metal, the roman numeral value from
  the group number is the positive value of the
  oxidation number.
• Example Hydrogen is in group IA therefore the
  oxidation number is 1 and the cation is written
  H1.
• OR
• If it is a nonmetal, subtract the roman numeral
  value from eight. Assign a negative sign to the
  oxidation number.
• Example F is in group VIIA 8 7 1 therefore
  the oxidation number is -1 and the anion is
  written F1-.
