The answer will be b. membrane.
Answer:
Because the oxidation state is an artificial number
Explanation:
The oxidation state is the charge that an atom would have if all its shared electrons belonged to the more electronegative atom, that is, if the bonds were completely ionic. This seldom happens.
For example, consider NH₃ and HNO₃.
Both compounds are covalent.
However, the N in NH₃ has an oxidation number of -3, because N is more electronegative than H.
Thus, N "gains" the three H electrons and gets a theoretical charge of -3.
The N in HNO₃ has an oxidation number of +5, because O is more electronegative than N.
Thus, N "loses" its five electrons and gets a theoretical charge of +5.
Because Na has one too many electron to be stable, while Mg has 2. once they loose those electrons, they will be come ion. loosing one electron will give the ion a 1+ charge, and loosing 2 will create a 2+ charge
