Below is an overview of the fundamental chemical principles that govern these elements. 1. Electronic Structure and Relativistic Effects Chemistry of Precious Metals
Gold's characteristic yellow color is a result of a relativistic shift that lowers the energy required for an electron to jump from the orbital, allowing it to absorb blue light. 2. Chemical Inertness and "Nobility" Au3++3e−→Aucap A u raised to the 3 plus

They possess high positive reduction potentials (e.g.,
