Rules for oxidation state
The oxidation state of an uncombined element is zero. This
applies regardless of the structure of the element:C, Xe, Cl2, S8,
and large structures of carbon or silicon each have an oxidation
state of zero.
The sum of the oxidation states of all the atoms or ions in a
neutral compound is zero.
The sum of the oxidation states of all the atoms in an ion is
equal to the charge on the ion.
The more electronegative element in a substance is assigned a
negative oxidation state. The less electronegative element is
assigned a positive oxidation state. Remember that
electronegativity is greatest at the top-right of the periodic
table and decreases toward the bottom-left.
For each of the following:
• Assign Oxidation States (Numbers) to each atom in reactants
and products
• Identify the species being reduced and the species being
oxidized
• Balance each redox reaction using the Half-Reaction method
O2 + ClO-2 -->
H2O + ClO2
Al + MnO-4 --> MnO2 +
Al(OH)-4
NO2- + Al --> NH3 +
AlO2

i am having trouble with that as well as to how...

In this reaction __________ is oxidized and __________ is
reduced
When the oxidation number increases, what does that mean about
the number of
electrons the atom has control over? In other words, if the
oxidation number
Increases is the atom getting oxidized or reduced
