Oxidation Numbers Flashcards
What is rule 2?
The oxidation number of a monatomic ion is the charge of that ion.
What is rule 3?
The oxidation of group one metals is +1 unless elemental.
What is rule 4?
The oxidation number of group 2 metals is +2 unless elemental.
What is rule 5?
Hydrogen is +1 when bonded to a nonmetal, -1 when bonded to a metal, 0 if elemental.
What is rule 6?
Oxygen is -1 in the peroxide polyatomic ion (rare), is -2 in all other cases, 0 if elemental.
What is rule 7?
Fluorine is -1, 0 if elemental.
What is rule 8?
The sum of all oxidation numbers in a compound equals 0.
What is rule 9?
The sum of all oxidation numbers in a polyatomic ion equals the charge of that polyatomic ion?
What is a peroxide?
