what colour is a gold atom
The colour of metals such as silver and gold is mainly due to absorption of light when a d electron jumps to an s orbital. For silver, the 4 d â5 s transition has an energy corresponding to ultraviolet light, so frequencies in the visible band are not absorbed.ith a single 6 s electron, you might expect gold to be highly reactive; after all, c sium has the same 6 s 1 outer shell, and it is the most alkaline of natural elements: it explodes if dropped in water, and even reacts with ice.
