some rocks are more reactive than others because of what theyve got in them.
Some rocks are more reactive than others due to differences in their mineral composition. Rocks that contain minerals that are chemically unstable or have a greater tendency to react with other substances will be more reactive. Additionally, the presence of certain elements or ions in the rock can also make it more prone to chemical reactions.
Cesium. Cesium is the bad boy of the alkali metals, a period that's just jam-packed with seriously nasty elements. Cesium is reactive enough that if you were to put some water into dry ice, and wait till the ice got that cold itself before putting some cesium on it, the cesium would still react with it! Here's a remembrance: the higher an alkali metal's atomic number, the more reactive it is.
Potassium is highly reactive, even explosive in some circumstances.
non-reactive
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
Quite the opposite: halides are far LESS reactive than halogens.A halide is a binary compound consisting of one halogen atom plus one atom, or radical, of "something else" that's electropositive to the halogen. (Which isn't hard to be.)Fluorine is a halogen, and it's very reactive. If you mix some sodium with it, it becomes a non-reactive halide; they put tons of this stuff in toothpaste and so far no one's reported having it cause their teeth to explode.Chlorine is also a reactive halogen, but mix it with sodium and it becomes table salt.
Some rocks are softer and more sedimentary than others. This allows water to weather them faster, thus causing higher permeability.
Some metals, notably potassium and sodium are highy reactive. Others eg bronze are much less so.
Yes. Some rocks have more space than others.
Manganese is not particularly reactive. This is strange considering it is more electropositive than its neighbors in the periodic table.
Depending on the minerals in their composition, some rocks are harder than others. Rocks that contain minerals with higher ratings on the Mohs scale are harder, and would erode more slowly than other rocks.

Some do others don't.
yes because more salt is dissolved at the bottom of the sea
There are many metals that are more reactive than zinc. To find out which these metals are, you can look at a reactivity series. Some examples of metals more reactive than zinc are sodium, potassium, magnesium & aluminium.
Some rocks cost 100 times more than others - and that's just plain rocks, not gems. So pick a rock, any rock.
because they have completely filled outer most energy levels
There are many reactive elements. They show up more on the upper left of the Periodic Table. Some of these are plutonium, uranium, Mercury and lead.
