Key Points
- Gold and copper happen to absorb blue and violet light, leaving yellow light in the spectrum.
- So gold and copper are yellowish in colour.
- The only two non-silvery metals in the world are gold and copper.
- A metal is defined as an element that readily forms positive ions (cations) and has metallic bonds.
- These elements have electrons that are loosely held to the atoms, and will readily transfer them.
- Most metals' electrons reflect all colours equally which are in the visible spectrum of light.
- So those metals appear as white silver.
