Oxygen.
Natural....it is a lanthanide and is a rare metal. This element can be found in minerals.
It is a rare earth element, never found in mineral deposits (veins and nuggets as with gold) but normally found in assocaition with other elements and minerals.
A salt or ester of sulfuric acid, containing the anion SO42− or the divalent group OSO2O. Sulfate is a compound found in nature. It occurs naturally in water in various amounts. If a high level of sulfate is in water, the water may have a bitter taste. Sulfates are also found in minerals, soil, rocks, plants and food. Sulfate is an acid not a gas though it could be turn into gas (if you had the right scientific apparatus.)
Individually, potassium and sulfur are elements and therefore are not ions when found in a pure state. However, K2S (potassium sulfide) is a compound that is formed via ionic bonds between the potassium and sulfur atoms.
