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.
Arsenic is not inert; it is a toxic element that can have harmful effects on living organisms. It is classified as a metalloid and has a variety of chemical forms, some of which are more toxic than others.
Potassium is the most reactive of the three metals (potassium, lithium, and sodium). It reacts vigorously with water, producing hydrogen gas and heat. Sodium is less reactive than potassium, while lithium is the least reactive among the three.
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
non-reactive
Scandium is a reactive element. It forms compounds with oxygen, halogens, and acids. While it is more stable and resistant to corrosion compared to some other reactive metals, it is not considered non-reactive.
Some rocks are more permeable than others due to differences in their porosity and pore connectivity. Rocks with higher porosity and well-connected pores have greater permeability, allowing fluids to flow through more easily. Factors such as grain size, sorting, and cementation also play a role in determining the permeability of rocks.
Some rocks are more easily weathered than others due to differences in mineral composition and structure. Rocks with weaker minerals or more porous structures are more susceptible to erosion from water, wind, and other environmental factors. Additionally, exposure to acid rain and high temperatures can also contribute to faster weathering of certain rocks.
Some metals, notably potassium and sodium are highy reactive. Others eg bronze are much less so.
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.
Manganese is not particularly reactive. This is strange considering it is more electropositive than its neighbors in the periodic table.
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
Some are, such as slate or coal. Others are not, such as chalk or halite.
