Gold is the most malleable of all metals. It can be drawn into a monoatomic wire, and then stretched about twice before it breaks. [citation needed] Such nanowires distort via formation, reorientation and migration of dislocations and crystal twins without noticeable single gram of gold can be beaten into a sheet of 1 square meter, and an avoirdupois ounce into 300 square feet.

Gold Mining Abundance of ore# Gold is extremely rare. According to geological experience essentially all gold is found only in low concentrations in rocks. Gold is rarer even than platinum, although because of platinum''s more even dispersion in the Earth''s crust it is actually harder to find commercial deposits of platinum. Gold is more frequently deposited in the concentrations which make
