for example: Zn has more tendency to oxidize than Ag, orZn has more tendency to be oxidized than Ag?

That is wrong! Can you directly quote the passage/sentence where it says this?BaO said:wait! how come my book says Zn has more tendency to oxidize than Ag?
Actually, this is not what a reduction potential table tells you. And in fact, Ag will not oxidize Zn (nor will Zn oxidize Ag). If you mix Ag and Zn, there will be no real chemical reaction at all; they will most likely form a nearly isomorphous alloy.sdekivit said:for the serie of metals in oxidation and reduction, a more nobler metal will always oxidize a less nobler metal.
--> thus Ag will oxidize Zn (you can also look this up in a table of standard electrode potentials)

However, Ag+ will oxidize Zn, while Zn2+ will not oxidize Ag.

magnesium has a higher tendency to oxidize than does iron?
Oxidation refers to a chemical reaction in which an atom or molecule loses one or more electrons, resulting in a positive charge. This process often involves the combination of an element or compound with oxygen.
Oxidation and reduction are opposite processes that occur simultaneously in a redox reaction. In oxidation, there is a loss of electrons, while in reduction, there is a gain of electrons.
While oxidation is commonly associated with the presence of oxygen, it can occur without oxygen as well. Some substances, such as chlorine, fluorine, and bromine, can act as oxidizing agents without the need for oxygen.
Oxidation plays a crucial role in many everyday processes, including combustion, rusting, and metabolism. It is also used in various industrial processes, such as the production of metals and chemicals.
There are several ways to prevent oxidation, including using protective coatings, such as paint or oil, to block oxygen from reaching the surface of a material. Another method is to use antioxidants, which can react with oxygen and prevent it from reacting with other substances.
