Arsenic is not found naturally pure. Arsenic and its compounds are found to be poisonous. It is used in insecticides and other poisons. It is also found in water.
Nickel is found pure in nature, in the ouskirts of Sudbary Ontairo. It can be obtained in a variety of ways with the help of manufacturing.
ground water and glaciers
Most of the elments are found as oxides and carbonates in the earths crust. The reason lies in the electropoositive nature of elements and high electronegativity of oxyg…en that they exist as compounds. The origin goes back to the evolution of earth when earth. However noble metals such as gold, platinum are found in pure form inside earth due to their low reactivity.
Pure water has a natural Ph due to the rate of dissociation to H+ and OH- is equal to rate of association to form H2O. Pure water has no free ions.
They are both very reactive so it is likely that they will have reacted with another element around them.
Because water is a great solvent for many things.
Water found in nature is never pure. Because of it's polarity, water naturally attracts most minerals. In order to get pure water, it must be filtered many times to remove all… the impurities.
Water that is in the form of clouds is relatively pure, although it does contain some dissolved pollutants from the air. Probably the purest you could find is old glacial ice …in Antarctica, deposited at a time when global air pollution levels were much lower.
There are lots of particulate debris in the air that eventually settle, and minerals within its surrounding environment.
Because it mixes with different things in the environment. Distilled water is pure.
Because they are highly reactive with many other elements.
yes, like places where there aren;t contamination
Platinum is found naturally, but is not "pure" in nature.
Mineral and ore originated form the molten rock or magma inside the earth. Magma or Lava is the solution of minerals and substances. Chance to have a non uniformly mixed miner…al in the molten rock solution is possible but usually rare because the property of solution to diffuse into each other until uniformly mixed.
