How can an object be charged?
a negatively charged repels a positivley charged object
How can uyour tell the atom has a positive charge?
All atoms have a positive charge, but the best way to determine a positive charge is to do an experiment. You take something positively charged and put it next to the atom. If it repels, it is positively charged. If it attracts, it is negatively charged.
What repels electric charge?
A negative charge will repel a negative charge.
How does a capacitor get charged?
a capacitor is used to store charge for longer period of time.in odder to understand that how a capacitor gets charged consider two parallel metal plates.these plates are neutral having equal amount of positive and negative charges.now connect these plates to the opposite terminals of a battery.the electrons present in the plate connected to the positive terminal of a battery will be attracted by the positive terminal leaving the plate positively charged.now these electrons are pushed by the battery to its negative terminal which repels these electrons to the plate connected to it making it negatively charged. now the battery is disconnected.so in this way the plates of a capacitor gets charged.as these plates have opposite charges stored on them force of attraction exist between them enabling a capacitor to store charge for longer periods of time.
Why do you get shocked touching a door knob?
You get shocked touching a door knob because of the friction between the carpet and the soles of your shoes. By walking across a rug or carpet, your body starts to become negatively charged because of the electrons picked up from the carpet. When you go to touch the door knob, your negative charge repels the electrons on the door knob, making the knob positively charged (the door knob becomes positive because of the exchange of electrons to the hand). Since positives attract negatives, your hand has a shock between the door knob because of the exchange of electrons. The only reason why there is an exchange of electrons is because the door knob is being neutrilized just like your body is releasing that small amount of electrons to make it have no charge.

A positively charged ion will bond with?
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
What happens when you bring a negatively charged rod near a piece of metal?
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.
What are some ways in which an object can become charged?
Some ways in which an object can become charged are friction, contact and induction.
A positively charged particle has great difficulty penetrating a target nucleus because the target nucleus has what?
a positive charge which repels the particle! ;)

What pairs of charged particles will result in a repelling force acting between the particles?
+ repels + , - repels - .
When 2 U-shaped big magnets touch each other what happens?
It depends on if they are charged the same of different. Opposites attract, the same charge repels.
What repels electric charge?
A negative charge will repel a negative charge.
How does current electricity move?
In a conductive material, the atoms have a number of electrons which freely move back and forth from atom to atom. When an electric potential is applied across the conductor, more electrons start moving in from the negative end. The extra negative charge repels the electrons that are already in the conductor, so they start moving towards the 'positive' end. Electrons are negatively charged, and like charges repel each other. Because there are negatively charged particles (the electrons) moving from negative to positive, we conveniently say that 'current flows' from positive to negative (there are these imaginary positively charged particles), but this is just a concept which makes it easier to think about, and not actually how it works.

Why are electrons not found in the nucleus?
The protons have a positive charge which repels them. The above is incorrect -- the positive charge of a proton would ATTRACT the negatively charged electrons. However, our Universe permits electrons within the electric field of a nucleus to exist only at specific orbitals in that field. An electron in a specific orbital has only an extremely small probability of being within the nucleus, and a far higher probability of being outside of it. Thus, electrons are outside the nucleus because the rules of our Universe -- those of quantum mechanics -- require that it not spend much time there.
