If a postivively charged rod is brought near the knob of a positively charged electroscope the leaves of the electroscope will?
separate further
Why must a sphere rod and leaves of an electroscope be a conductor?
When a negatively charged rod touches the sphere of the electroscope, negative sharge spreads throughout the metal. Since the leaves are both negatively charged, the free ends repel and move away from each other. When a positvely rod touchs the sphere, negative charges move toward the sphere, causing the leaves to be positively charged. hope this helps :)
How can gold leaf electroscope be used to detect an electric charge?
In order to identify the charge of a body we should use a charged electroscope. Let us say the electroscope is negatively charged. Now bring the unknown charged body 'X' near the cap of the electroscope. If the leaves diverge more the charge in 'X' must be negative. Suppose that the leaves close a little when 'X' is brought near 'C', then 'X' may have a positive charge or it may not have any charge. In order to confirm the positive charge you must bring the rod 'X' near the cap of a positively charged electroscope. If the leaves diverge more, then 'X' has positive charge.
Can the leaves of a metal leaf electroscope be attracted to each other?
No. There is only one connection for the leaves. They are either charged (spread apart) or not charged (not spread apart).
What happens to the leaves of an electroscope that is not charged?
They hang limp.
Attraction and repulsion?
Attraction and repulsion, in physics means, is when two objects attract and repel one another. For example, an When a negatively charged rod is brought near an electroscope with negatively charged leaves, the leaves will repel. Same goes for when a positively charged rod is brought near an electroscope with positively charged leaves, the leaves will repel. But if a negatively charged rod is brought near an electroscope with positively charged leaves, the leaves will attract. Kind of like opposites attract, and likeness repels.

Why do the leaves of an electroscope repel each other when a charged object touches the knob?
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.

What happens with electrons when objects become positively or negatively charged?
The same thing happens for both, if the electroscope is positvely charged it attracts electrons to the top and sends protons to the leaves causing them to repel and visaversa with negative.
When a rod is brought near a neutral electroscope the leaves diverge what best describes the charge on the rod?
it may be positive or negative hope this helped :)
Does a radioactive particle moving through the air near an electroscope cause the leaves of the electroscope to move together?
when the radio active particle moves through the air, it gets charged. As a radio active particle gets negative charge, and the air around it gets positive charge, then the few electrons from the negatively charged particle goes to positively charged one to make the charges equal. (the more friction you apply, the more charge it gains) now the radio active particle gained positive charge compared with other particles. If the radio active particle flows over the electroscope and is near it within a limit, then the leaves may move together if the electroscope had been charged negative, else the leaves are charged positive then the leaves would diverge further . as the radio active particle is not actually touching the electroscope, the radiated energy from the radio active particle reaches the electroscope, and hence the charges would not transfer but the effect would be there until you take the radio active particle away. answered by K.Sreram from India
What if the electroscope leaves hang down?
they are not charged
What is the charge of an atom that gains an electron?
since electrons are negative, you would subtract one from the original charge of the atom. For example, is the atom was neutral, the charge would then be 1-
