Why are metals colored?
Metals are colored because the absorption and remission of light are dependent on wavelength.Gold and copper have low reflectivity at short wavelengths yellow and red are preferentially reflected as the color suggests.
Why are metals magnetic?
Magnetism in metals is created by the uneven distribution of electrons in atoms of certain metal elements. The irregular rotation and movement caused by this uneven distribution of electrons shift the charge inside the atom back and forth creating magnetic dipoles.
