Solution
Gold does not get electrically charged easily by rubbing.
Explanation:
Gold does not get electrically charged easily by rubbing because it has a low tendency to lose or gain electrons. This is due to its high conductivity and stable atomic structure, which makes it less likely to accumulate static charge compared to materials with higher electron affinity or lower conductivity.
