How is an element's most likely oxidation state related to its valence electrons
🔄 Click to see definition
Definition1/15
In an atom of an element has one or two valence electrons and is
not a helium atom, the most likely oxidation state is positive by
the number of valence electrons, while if the atom of an element
has seven or six electrons, the most likely oxidation state is
negative by the number of electrons required to total eight valence
electrons. Helium and all the atoms with eight valence electrons
have a most likely oxidation state of zero, corresponding to no
reaction.
