Why is gold used in the gold leaf electroscope? - Quora

Jan 16, 2018 · Because gold is unequaled when it comes to ductility. A leaf electroscope requires a minimum weight in the leaves, so that the very weak force exerted by practical voltages will cause significant separation. While gold is one of the densest metals.

Gold Foil Electroscope - Ward's Natural Science

This high sensitive electroscope can detect charges that a regular electroscope cannot. A gold leaf is mounted on an insulated rod in a grounded metal case, and the glass windows at the front and back of the case allow for easy observation or projection. It is a good alternative for high humidity environments.
