Key Differences
- ◆ Gold has a golden-yellow color and streak; silver is white and tarnishes to gray or black.
- ◆ Gold has a much higher specific gravity (15.6–19.3) than silver (10.1–10.5).
- ◆ Silver is the best conductor of electricity; gold is highly corrosion-resistant.
- ◆ Both are native elements, cubic, and have hackly fracture, but gold is more malleable.
- ◆ Silver forms wire and dendritic habits more readily; gold occurs as octahedral crystals, nuggets, and flakes.
