Hapetusasteella
Hapetusasteella, often translated as oxidation state, is a concept used in chemistry to describe the hypothetical charge that an atom would have if all of its bonds to atoms of different elements were 100% ionic. It is a bookkeeping tool that helps chemists track the transfer of electrons in chemical reactions and understand the properties of compounds.
The oxidation state is assigned based on a set of rules. For example, the oxidation state of
Changes in oxidation states indicate a redox (reduction-oxidation) reaction. When an atom's oxidation state increases, it
