Oxidation
Gold is highly resistive to damage cause by oxidation, which means it doesn't rust easily. This is why it is often used in electronics or dental work.
Melting and Boiling
Pure gold can withstand high heat and has a melting point of 1947.52 degrees Fahrenheit. It will begin to boil at 5173 degrees Fahrenheit.
Density
Pure gold is found in a solid phase with a density of 19.3 g times cm-3. When under extreme heat, it becomes less dense as it melts.
Toxicity
Unlike many other types of metals, pure gold is completely non-toxic. In fact, it is sometimes used for decoration in drinks and on food.
Magnetism
Pure gold is a diamagnetic metal. This means that when a magnet force presses against it, it creates a magnetic force of its own that repels it.
