Question

why gold is taken in gold leaf electroscope

Answer 1

Because they are malleable.

Explanation:

Gold is not the only metal used in electroscope. Copper is also used in electroscope.

A reason why these metals are used is that they are malleable more than any other metal. To use the electroscope, you need to put a thin trey into it.

Another reason, which is not the best and is not quiet sure to me, is that Gold is less reactive. If you put a highly reactive metal as trey's substance, then that metal will react with the electrons that pass through it and will leave the observer a hard chance of having a good view.

Answer 2

Answer:

see the explanation and you will understand

Explanation:

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, it can also be hammered into thinner leaves than any other. The thinness overcomes the density, so gold leaves (at minimum thickness) are lighter than can be produced by any other metal.
