Covalent radiusHalf of the distance between two atoms within a single covalent bond. We group minerals into classes on the basis of their predominant anion or anion group. The native elements contain the most gold, followed by the sulfide minerals. Where more than one isotope exists, the value given is the abundance weighted average. The effect was seen as magical, a devilish art. When quartz is found in gold bearings areas, it is possible that gold will be found as well.
