Answer:
This equation represents oxidation reaction.
Or
This equation is also representation of ionization of atom.
Explanation:
The oxidation is a chemical reaction where an atom loses electrons or gain oxygen or loses hydrogen.
Due to loss of electron or hydrogen or gain of oxygen there is an increase in its oxidation state.
i) it changes from negative to zero
ii) it changes from negative to positive
iii) it changes from more negative to less negative
iv) it changes from zero to positive
v) it changes from less positive to more positive.
In the given reaction the metal loses electron and gets oxidized.
We can also that the metal gets ionized.
