Why does silver turn black while gold stays shiny forever? In this video, we explain in simple words why silver tarnishes and gold does not. You'll learn why the black layer on silver is not rust, how traces of hydrogen sulfide in ordinary air turn silver into black silver sulfide, why gold is called a noble metal, and the surprising real answer to gold's unreactivity: Albert Einstein's theory of relativity. Along the way, you'll discover why that same relativistic effect makes gold yellow and mercury liquid, and why gold coats the connectors inside your phone and the visors of astronaut helmets. Whether you're a chemistry student, a curious science fan, or someone who just found a blackened silver spoon in a drawer, this explainer breaks down tarnish, noble metals, and relativistic chemistry into ideas anyone can follow.
