We arrange metals into an ordered list with the best reducing agent at the top and the worst reducing agent at the bottom. This is an Activity Series for metals. Metals near the top of the list give up electrons most easily. Those metals near the bottom of the list give up electrons with difficulty. Hydrogen, even though it is not a metal, can be placed in the list. Metals above hydrogen in the Activity Series will react with 1.0 Molar hydrochloric acid at room temperature. The Activity Series for metals is developed by experiment.A list of metals arranged in order of reactivity~APEX
When an acid reacts with a metal, the products are a salt and hydrogen gas. The metal displaces hydrogen from the acid, forming the salt (metal chloride, sulfate, etc.) and releasing hydrogen gas.
When lithium reacts with potassium hydroxide (KOH) solution, lithium hydroxide (LiOH) and hydrogen gas (H2) are produced. The chemical equation for the reaction is 2Li + 2KOH -> 2LiOH + H2. The lithium hydroxide formed will dissolve in the KOH solution to give a clear colorless solution.

Plot
The activity series of metals lists the metals in order of reactivity, with the most reactive metals listed at the top, and the least reactive metals listed at the bottom. When determining the results of a single replacement (displacement) reaction, you compare the two metals according to their location on the list. If the elemental metal is higher on the list, it will replace the other metal in the compound. For example, Al + 3AgNO3 --> 3Ag + Al(NO3)3 occurs because the metal aluminum, Al, is higher than silver, Ag, on the metal reactivity list, and replaces the silver in the silver nitrate, AgNO3, to form elemental silver, Ag, and the compound aluminum nitrate, Al(NO3)3. The reverse reaction, 3Ag + Al(NO3)3 --> Al + 3Ag(NO3)3 will not occur, because the silver is lower on the list than aluminum, and cannot replace the aluminum in the aluminum nitrate, so the correct equation is Ag + Al(NO3)3 --> n.r. (which means "no reaction").
Metals give up electrons while non-metals gain electrons
They are the Alkali Metals, Alkaline Metals, Transition Metals, Metalloids, Halogens, and the Noble (Inert) Gases. There is also the lanthanide and actinide series which are known as the Rare Earth Metals.

Metals usually have a characteristic lustre, so you can often tell just by looking. The metals conduct electricity when solid, and non-metals, with the exception of graphite, do not. Metals react with oxygen to give basic oxides, whereas non-metals give acidic oxides.
