Ask AI — Gold (Au)
Why is gold used in electronics?
Gold is the perfect conductor for electronics because it never oxidises or corrodes — even after decades of use. Unlike copper or silver which tarnish over time, gold contacts stay clean and conductive forever. That is why it coats the pins on every CPU, smartphone connector, and satellite circuit.
How rare is it really?
All the gold ever mined by humanity would fit into roughly 3.5 Olympic swimming pools. It makes up only 0.0000004% of Earth's crust…
