If you look again at this very reaction, you might notice that Fe is not the only element to change its valency here; S does the same. Reactions like this one are called redox reactions. WebIn chemistry, valence (sometimes called valency) is the characteristic of an element that governs the number of other atoms with which it may combine. The phrase was coined in 1868 to indicate both the overall capacity of combining an element and the numerical magnitude of that power of combination. The combining power of an element is known …
