(C) Metals that are at the bottom of the reactivity series are the least reactive. These metals are often found in a free or native state in nature because they do not react easily with oxygen,moisture,or other substances in the environment. Gold $(Au)$,silver $(Ag)$,and platinum $(Pt)$ are examples of such metals. Iron $(Fe)$,Aluminum $(Al)$,and Calcium $(Ca)$ are more reactive and are typically found in the form of oxides,sulfides,or carbonates (ores).
