I don't know if the title explains it enough, but I will try to make it clearer.
Metals have the attribute of giving away electrons while fusing with nonmetals, acids, (In Redox reactions which I am studying in school now) and in many more processes i presume; in order to achieve a stable electronic configuration of a noble(Inert) gas(Which is placed before the current element in the Periodic Table), and the nonmetals are gaining those electrons in order to do achieve a stable electronic configuration of a noble(Inert) gas(Which is placed after the current element in the Periodic Table). And now there is a chemical rule that every metal which is placed on the left side of the hydrogen is able to extrude the hydrogen from a compound and take its place(During that process the hydrogen is unleashed in the еnvironment freely). There is a list of the most common metals who can extrude/who can't extrude the hydrogen. Here is what i have:
Li, K, Ca, Na, Al, Zn, Fe, Cd, Ni, Sn, Pb, H2, Cu, Ag, Hg, Au
If someone knows, please tell me where to find the full list of these metals.
