Uncharged means that there are an equal number of protons and electrons. When the negative rod is held near the neutral metal ball, the electrons from the metal ball repel from the electrons on the rod bringing the protons closer to the rod causing the metal ball to be attracted to the negatively charged rod. It's called charging by induction.
-- If the pith ball had a negative charge when you arrived, then
it will be repelled from your negatively charged object.
-- If it had either a positive charge or no charge when you arrived,
then it will be attracted to your negatively charged oject.
The negative charge repels the electrons on that side of the ball.
protons in the metal move toward the rod.
becomes charged by conduction
it will not do anything
electrons in the ball will move away from the ruler to the furthest side of the ball
toes
conduction
No. It is not possible. Because as soon as balloon touches the metal charges would be conducted.
Any material can be charged, either positively or negatively. It has no name as such. You can do that by shuffling your feet back and forth on a carpet and touching something. You can feel a spark from your finger. By shuffling your feet your body acquires a charge, which discharges when you touch a metal object that is grounded.
Charged rod and an uncharged metal object attract each other because free electrons in metal are either attracted or repelled by the charged rod. If the rod is positively charged then free electrons are attracted towards it and both objects attract each other. If the rod is negatively charged then free electrons are repelled by it and positive ions are attracted by the rod and both objects attract each other.
Not only magnets, but metal repel. There are two kinds of charges that metal contain, positive and negative. If you push a positively-charged magnet towards another positively-charged magnet, they'll repel, maybe because one type of charge needs the other to attract. If this one type of charge comes close to another charge of the same kind, it won't receive what it needs, and feel "resent" to the other charge, then repel. If you push a negatively-charged magnet towards another negatively-charged magnet, they will also repel.
It accepts electrons from the metal and forms a negatively charged ion
Metals lose electrons to become positively charged but stable. The electrons they lose are accepted by the non-metal to become negatively charged but stable.
It is an oxidation/reduction reaction. The metal loses electrons to become positively charged (it is oxidized) and the oxygen gains those electrons to become negatively charged (it is reduced). You end up with a metal oxide.
Negatively charged.
Metal ions are typically positively charged, while nonmetals are typically negatively charged.
An Alpha particle
conduction
Monatomic ions of metals are positively charged and monatomic ions of nonmetals are negatively charged.
an ionic compound is made of positively charged metal ions and negatively charged non-metal ions. they usually form an ionic lattice.
The electrons are shared between the atoms. An ionic bond occurs between a metal and a non-metal. The metal donates one or more electrons to the non-metal, causing the metal to have a positive charge. When the non-metal accepts the electrons, it becomes negatively charged, thus resulting in an attraction between the two charged ions, and forming a bond.
protons in the metal move toward the rod.
Yes, because metal conduct electricity.
