oksidiluvut
Oksidiluvut, also known as oxidation states or oxidation numbers, are a bookkeeping tool used in chemistry to track the hypothetical charge that an atom would have if all its bonds to atoms of different elements were purely ionic. This concept is particularly useful in understanding redox reactions, where electrons are transferred between species.
In an elemental substance, the oxidation number of each atom is zero. For simple monatomic ions, the
There are several general rules for assigning oxidation numbers in compounds. For instance, oxygen usually has
The concept of oxidation numbers helps identify which species are oxidized (lose electrons, oxidation number increases)
