Grounding a Negatively Charged Electroscope
While the negatively charged electroscope is touched and its charge becomes grounded or neutralized this is depicted within the animation below. The grounding procedure includes a transfer of electrons among the charged electroscope and the conducting object to that it is touched. While a negatively charged electroscope is touched electrons leave the electroscope to the ground. Since electrons repel another electron, their tendency is to spread out as far as possible by any conductor.
