oxidation numbers

Atomic charge assignments

Oxidation numbers are values assigned to atoms in molecules or ions to track electron transfer in chemical reactions.

An atom that loses electrons has a positive oxidation number; one that gains electrons has a negative number.

The concept simplifies balancing redox equations and predicting reaction products.

In water (H₂O), hydrogen has an oxidation number of +1 and oxygen −2.
