what does it mean when you see a battery for example, is positively charged and negatively charged?

On a battery, you have two terminals- a positive and a negative.  As a result, the net charge is 0.  Also, a battery is the source of 'power' in an electrical circuit, it is direct current (DC) instead of alternate(ing) current (AC).  The battery produces a certain number of Volts and from that, you can find the current at different points in the circuit, as well as the number of amps.  (I hope this is what you are talking about)

I like the previous answer, and bobo the king's answer on monopoles as well. However, I thought I might expand on them a bit and make a couple of comments:\n\nA simple understanding of electrical charges is easy, but a deep understanding of electrical charges is quite challenging. We can give examples of electrical charges. The smallest unbound charge we have observed is the charge on an electron or on a proton. Electrons and protons are oppositely charged particles, and so by the laws of electromagnetism, they attract each other. However, two electrons are charged the same so they repel each other, as do two protons. \n\nThe electron charge is negative in our convention, and is about -1.60217646 × 10^(-19) coulombs. The proton charge is positive in our convention and is about +1.60217646 × 10^(-19) coulombs. \n\nHowever, at this point, no one really understands what an electrical charge is, or what causes it. We know that the weak, strong and electromagnetic fundamental forces are produced and transmitted by the exchange of messenger particles; in the case of electromagnetism, these messenger particles photons. We know that there appears to be some deep connection between these 3 fundamental forces; in other words, the weak, strong and electromagnetic forces all appear to be different aspects of the same thing.\n\nMagnetic forces are due to the movement of electrical charges, by the Biot-Savart Law. Electrical charges moving in loops result in electomagnets, which are the basis of a lot of technology, such as electric motors. However, a postulated fundamental unbound magnetic charge, known as a magnetic monopole, has never been observed yet. No one really knows why there are unbound fundamental electrical charges but not magnetic charges (or at least we have not seen them yet). \n\nI am not sure what an electromagnetic charge is. I did some web searching, and I find that this term is used by some who really mean electrical charge, and has been appropriated by assorted pseudoscientists and mystics for their own purposes.

A cation (not kation) is an ion with a positive charge and an anion is an ion with a negative charge. What exactly do you mean analysis? Hope it is somewhat helpful.

cation, a negatively charged ion would be an anion...

Materials do not havae charges. When electrons are rubbed off or on then they get a charge. Skin does not hve a positive charge. Saran wrap is not charged until electrons are transferred to or from it.

Because positively and negatively charged ions exist. Because electrons exist.

Charge is a property of atomic particles, the buidling blocks of matter. It can be positive (proton), negative (electrons) or neutral (neutron). Molecules can also be charged. Charges cannot be created or destroyed, they can only be added or subtracted (by adding or subtracting electrons usually). Its like the color of your hair. It could be brunnet, red or black. You can add pigments or it can fade several days later. But you cannot change a person's hair color permanently (of course some turn white when they get old though). So in this sense it is invariant.

Positive cable  = + = red cable. look for a plus + sine on the battery.

It's either just one charge: The electrical, which appears in positive and negative characteristics, or if you see "charge" in a more general way it's more then one charge: magnetism has also a source, but that appears always in dipoles, mass is the "charge" of gravity, but that appears just with a positive sign, and the strong interaction has three kind of charges, called "colour charges": red green and blue.\n\nTwo see an underlaying principle for this "chaos" we need the "Grand Unified Theory" which still is "work in progress" ;)

Answer is a) that a positive test charge would move.\n\nElectric field lines from an isolated charge move towards the negative charge , that is outwars from an isolated positive charge and inwards from an isolated negative charge that means if a positive test charge is released it will move along the electric field line , that is positive to negative.  So a) is the correct answer.\n\nThis pic will help you visualize it :\nhttp://buphy.bu.edu/~duffy/PY106/2e.GIF\n\nHave a nice day.\n☺☺☺\n\nCheck out this link for further clarification .

larger...a negative ion has an electron added that the neutral atom does not have.

it appears to be the name of the CO-2 ion. (-2 is the charge).

Thats simple,\nAs we rub together two surfaces, there is friction and hence the two close atoms are rubbed together which results in transfer of electrons...\nThe subs in which electrons are transfered is negatively charged (by convention electrons are supposed to have negative charge) and from which they are transfred is said to be positivly charged...

None of the above.\n\nIt will repel another positive change,\nattract a negative charge,\nand not interact with a neutral charge.

battery\nn. the actual intentional striking of someone, with intent to harm, or in a "rude and insolent manner" even if the injury is slight. Negligent or careless unintentional contact is not battery no matter how great the harm. Battery is a crime and also the basis for a lawsuit as a civil wrong if there is damage. It is often coupled with "assault" (which does not require actual touching) in "assault and battery."\nassault and battery\nn. the combination of the two crimes of threat (assault) and actual beating (battery). They are both also intentional civil wrongs for which the party attacked may file a suit for damages.

C, having both positive and negative charges on one molecule.

I think that refers to the type of battery that it contains.
