Gold Properties

• Gold conducts heat and electricity.
• Gold is ductile: It can be drawn out into the thinnest wire.
• Gold is highly reflective of heat and light.
• Gold is prized for its beauty.
• Gold is malleable, so it can be flattened into extremely thin sheets.

  Why is gold not flammable?

  Elemental gold is not flammable. Flammability requires elements to be able to unite with oxygen in a combustion reaction. The inert electronic configuration of gold makes it unreactive with oxygen even in molten form. The special inertness of gold results from its having a single outer electron in an s orbital.

  Are there any health risks associated with gold?

  Hazards and Risks. Hazards and risks associated with gold: gold is not absorbed well by the body and its compounds are not normally particularly toxic. Up to 50% of arthritic patients treated with gold-containing drugs (see above) may show toxic effects however resulting in damage to the liver and to the kidneys.

  What are the effects of gold on the environment?

  Environmental effects of gold. Gold has not been evaluated for its ecotoxicity. However, the biodegradation of gold under aerobic conditions is expected to be very poor and there is no evidence to suggest it creates ecological problems when released into the environment.

  What are the physical and chemical properties of gold?

  Chemical properties of gold – Health effects of gold – Environmental effects of gold Atomic number 79 Atomic mass 196.9655 g.mol-1 Electronegativity ccording to Pauling 2.4 Density 19.3 g.cm-3at 20°C Melting point 1062 °C

  Are there any harmful effects of gold nanoparticles?

  Toxicity of gold nanoparticles, for instance, has been shown at high concentrations. In addition, nanoparticles trapped in the liver can affect the function of this organ. Nanoparticles have the potential to cross the blood brain barrier, which makes them extremely useful as a way to deliver drugs directly to the brain.
