why gold is found in free state but iron is not Science

Gold is the least reactive metal. It does not react with O, C ,CO 3 etc. to form any compound and hence always found in free state.. Fe is a reactive metal . It react with the atmospheric oxygen to form oxide and thus it is mostly found in oxide form.

why gold silver and platinum exist in free state

This is because metals like platinum,gold and silver are noble metals,they do not easily mix with impurities such as silica,potassium etc. And even if they do mix it can be easily separated by adding a acid to it.Hence, these metals are present in free state.

Why is gold found in a native state? Quora

Gold is very stable. It doesn't have a tendency to combine or corrode (oxidize). We all know how easily iron rusts, copper turns blue, even silver needs to be polished to remove tarnish. Rusting is what happens when a metal combines with oxigen. G...

native element Definition & Examples Britannica

17-08-2020· Native element, any of a number of chemical elements that may occur in nature uncombined with other elements. The elements that occur as atmospheric gases are excluded. The native elements are commonly divided into three groups—namely, metals, semimetals, and nonmetals.

Native metal Wikipedia

Native silver occurs as elongated dendritic coatings or irregular masses. It may also occur as cubic, octahedral, or dodecahedral crystals. It may occur alloyed with gold as electrum.It often occurs with silver sulfide and sulfosalt minerals. Various amalgams of silver and mercury or other metals and mercury do occur rarely as minerals in nature.

Gold Wikipedia

Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Silver: A native element, mineral, alloy, and byproduct

Silver as a Native Element Mineral. Silver is rarely found as a native element mineral. When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals.Unlike gold, it is rarely found in significant amounts in placer deposits.

Gold: The mineral native Gold information and pictures

Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is.

Gold Geoscience Australia

Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold. This is referred to as 'native gold'.
