Day 7 notes
Record the following notes on page 6 of your foldable
How to determine oxidation numbers1. Find the group number (roman numeral) for the element
(located at the top of the group).2. Determine if the element is a metal or a nonmetal.
1. 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
2. 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-.
