0 in elemental form, +1 in all its compounds
Sodium is a highly reactivated element. It shows +1 generally when combined.
Sodium is a highly reactivated element. It shows +1 generally when combined.
The most common oxidation number of magnesium is +2.
the most common oxidation number for oxygen is -2.
Chlorine is in group 17. It easily accepts an electron from another element to fill its valence shell. As it takes one electron, its oxidation number changes to -1.
+4 is the most common and the most stable oxidation number
-1 is most common in chlorides. However chlorine can exhibit oxidation numbers up to +7 in its compounds.
