If a negatively charged rod touches a neutral electroscope, electrons will flow from the rod to the electroscope, causing the electroscope to become negatively charged. The leaves of the electroscope will repel each other, indicating a charge has been introduced.
When a negatively charged rod touches a neutral electroscope, electrons transfer from the rod to the electroscope, causing the electroscope to become negatively charged. This results in the leaves of the electroscope repelling each other and spreading apart, indicating the presence of an excess negative charge.
When a negatively charged object touches a neutral object, electrons transfer from the negatively charged object to the neutral object, causing the neutral object to gain electrons. This results in the neutral object becoming negatively charged.
When a charged object touches the metal knob of an electroscope, electrons are either transferred to or from the electroscope, causing the metal leaves to gain a net charge. Like charges repel each other, so the leaves spread apart due to the repulsion between the negatively charged leaves. This spreading apart indicates the presence of an electric charge on the electroscope.
When the knob of the electroscope touches a positively charged object, electrons from the object are transferred to the electroscope, causing it to become positively charged. This causes the gold leaves to repel each other due to the like charges, spreading apart and indicating the presence of a positive charge on the electroscope. A diagram would show the initial position of the gold leaves close together, then spreading apart when the electroscope becomes positively charged.
When a charged object touches the metal knob of an electroscope, electrons are either transferred to or from the electroscope. This results in an imbalance of charge between the metal knob and the leaves, causing them to repel each other due to the like charges. The leaves spreading apart is a visual indication of the presence of charge on the electroscope.

Because when the charged object is say, negatively charged, the electrons in the electroscope want to get as far away as possible from the negative object because "like" charges REPEL. so when the electrons in the electroscope move to the leaves , they now are both negative and "like" charges so now the leaves want to get away from each other as well and that's why they separate.

When a positively charged body touches a neutral body, the neutral body will become positively charged due to the transfer of some positive charge from the positively charged body.
When a charged body touches the gold leaf electroscope, electrons are transferred between the body and the electroscope. This causes the leaves to have the same charge and repel each other due to the like charges, causing them to move apart. The increased separation distance between the leaves makes them appear to expand.

The sphere of an electroscope is always neutral at first. Let's say a negative ebonite rod is brought close but not touching the sphere. (The entire electroscope is neutral). The electrons in the electroscope will want to repell the electrons in the rod so the electrons in the electroscope move down into the 2 leaves and then repell because there is a high concentration of negatives. When the ebonite rod is removed, the leaves go back to their straight position. The electroscope is always neutral but only a charge distibution occured. The number of protons and electrons remain the same. However if a charged rod touches the sphere then the electroscope will be charged because it a conductor and the charge from the rod transfers to the electroscope because the rod's caharges want to attarct to the electroscope's opposite charges. This is called charging by contact.
When a charged object touches the metal knob of an electroscope, it transfers some of its charge to the electroscope, causing the leaves to acquire the same charge. Like charges repel each other, so the leaves spread apart from each other due to the repulsive force. This demonstrates the presence of excess charge on the electroscope.
the charged rubber rod transfers some of its charge to the electroscope, causing the metal leaves to repel each other due to the like charges they now possess. This movement is a result of the mutual repulsion of the charges on the metal leaves.
