Flashcards in Redox reactions Deck (15)
addition of oxygen/ loss of electrons
loss of oxygen/gain of electrons
a species that receives electrons from another species, receiving one or more electrons, meaning it is therefore reduced.
a species that donates electrons to another species, donating one or more so that it is then oxidised
the charge that an ion has or the charge it would have if it were fully ionic.
oxidation number of uncombined element
sum of oxidation numbers of neutral compound
sum of oxidation numbers of all elements in an ion
CHARGE OF THE ION
oxidation number of more electronegative ion in a substance
oxidation number of fluorine
oxidation number of hydrogen
+1 unless combined with a less electronegative element when is -1)
oxidation number of oxygen
-2 (except in peroxide when is -1)
what happens to oxidation number in oxidation?
what happens to oxidation number in reduction?
