Since is in column of the periodic table, it will share electrons and use an oxidation state of . -The oxidation number for O is -2 most of the time - for a neutral molecule, the sum of the oxidation number = 0. 2. Still have questions? Should I call the police on then? The oxidation number of an ion indicates the number of electrons that an ion can gain, lose, or share when chemically reacting with another ion (monatomic or polyatomic), atom, compound, or molecule. 208!!

The algebraic sum of the oxidation numbers of elements in a compound is zero. O is -2 ==> -2. Also note that the oxidation number of C in formaldehyde (CH 2 O) is the same as it is in sugars ({CH 2 O} n) i.e. The convention is that the cation is written first in a formula, followed by the anion. Just a heads-up. ∴ x = +2. Find the Oxidation Numbers C_2H_3O_2. ∴ x+3−2+1 = 0. Theoritically it seems that C has +2 oxidation number in this compound. In NaCl, sodium has an oxidation number of +1, while chlorine has an oxidation number of −1, by rule 2. Oxidation is the loss of electrons or the increase in oxidation number, so CH3OH is oxidized.
