Hello to all friends

My question is
Gold metal in the soil over time following their positive ions are produced or negative ion ??????
Note that the name ions are attracted to each other you'd be pregnant with two brass rods out of place to identify ion.
Thanks!

Soil (moisturized) is the electrolyte, gold act in it only as electrode, what electrode is and what ions emitted depends on the other electrode in the vicinity (battery efect). But if we speak about static charging of gold in soil, generally all metals in soil are negative charged.

Simple answer: Buried gold ions are positive.

Detailed answer:
WM6 is correct that buried gold metal usually has a negative charge compared to the air above. The earth is negatively charged while the atmosphere is more positive, which causes a small amount current to leak from the earth through the air toward the ionosphere. The earth is eventually replenished with more its charge during thunderstorms, which keeps the ground from fully discharging from leakage through the atmosphere. Any conductive objects buried in the ground will take the same negative charge of the ground around them. In cases where there are two different kinds of metal buried near each other, a ground battery can develop to send a current through the electrolytes in the soil. It is as WM6 said. The relative charge and voltage of the gold will depend on the other metals nearby.

A small amount of gold can also dissolve in the soil even if there is no other metal object nearby, due to chemical corrosion. There are natural chemicals in the soil that dissolve gold and cause it to ionise in very tiny amounts that can be measured in the parts per trillion or less. This is not enough concentration of gold ions to measure with ordinary instruments except by taking soil samples to a laboratory for chemical analysis. These trace amounts of ions are positive, but can exhibit several oxidation states between -1 and +5.

The oxidation state we usually find gold ions dissolved in the ground is +1 for aurous compounds. A good example is aurocyanide Au(CN)2− which can form when natural sodium cyanide or potassium cyanide are present in the soil where the gold is buried. Gold ions with the +1 oxidation state can also be suspended in sulfur complexes derived from natural organic acids in the ground. In these cases the gold corrodes into an ion in the soil with a charge of +1, which means it is a positive gold atom which is missing an electron.

At best, you can expect to find around one part per trillion of these positive gold ions dissolved in damp soil. The only negative valence state is -1 for the aurides such as caeseum auride, Tetramethylammonium auride, rubidium auride, and other exotic compounds you probably will never find in your treasure hunting fields. You will find mostly +1 positive gold ions near a gold object that has been buried a long time. And You probably won't find those unless you have a way to find buried gold ions less than a part per trillion. :rolleyes:
