because most reactive metals don't last long in their unbonded state, and will dissipate or react fast, most of the elements we found were in bonded states, and we separated them, while non reactive metals are quite stable by them selves, and would last longer in the open air.
For the main area the reactivity of metals decrease their fee. distinctly reactive metals are efficient to the chemical industry to make compounds. Metals that are very unreactive like gold and platinum are very efficient as jewelry. Semi metals or semi conductors are efficient to the electronics industry. Reactivity even with the incontrovertible fact that via itself has no touching on fee, what impacts fee is supply vs call for. If there is greater call for than supply it places upward stress on the fee, if call for is low and supply substantial it places downward stress on the fee.
Most metals do not exist in metal form in nature. They form oxides or sulfides. What is dug from mines is roughly a rock containing some percent of the metal in oxide form or others. Iron can be usually found as magnetite (Fe3O4) and hematite (Fe2O3); Titanium as TiO2 etc. But noble metal which are less reactive or not reactive at all such as gold, platinium, silver can be found as metals. So you can find a piece of gold in the nature but not titanium. (iron can only be found in some meteorites). So gold was one of the first metals to be discovered. Then as the metal becomes more reactive it is harder to extract it from the oxide or other compound, and it necesitates a more advanced understanding of chemistry. So as chemistry advanced, more reactive metals were discovered.
