Old (very old) tradition, when electricity was assumed to flow from positive to negative.

(They hadn't figured out electrons yet.)

What objects with equal amounts of positive and negative charge are said to be electrically?

An object with equal amounts of positive and negative charge is electrically neutral.


Compounds that have the same number of positive and negative charges are said to be?

Compound having any positive or negative particle are said to be charged particle . it is not so that there should be same number of positive or negative infact these are called saturated particle .an atom carring positive particle are called cationwhile negative particle are called anionby MK


How do charges move in a circuit?

Along a loop with no beginning and no end.


The overall charge of the nucleus is?

The overall charge of a nucleus is positive. The nucleus is consisted of protons and neutrons. Protons have a positive charge and neutrons have a neutral charge. Electrons have a negative charge but are located in the shell orbiting the nucleus, so their charge is not included in the nucleus' charge. Since the only particles in the nucleus either have a positive or neutral charge, the nucleus will always be positive.


Who named the two types of charges?

There are two types of electrical charges. Positive and negative. These are decided by the natural balance of the atoms they involve, with protons being positive, and electrons being negative. So a negative charge would be an excess of electrons, and a positive charge would be a deficiencies of electrons. This un-conventional theory.In electronics, they say a positive charge is an excess of electrons; and a negative charge is a deficiencies.I took this definition from Wikipedia.Formal definitionMore abstractly, a charge is any generator of a continuous symmetry of the physical system under study. When a physical system has a symmetry of some sort, Noether's theoremimplies the existence of a conserved current. The thing that "flows" in the current is the "charge", the charge is the generator of the (local) symmetry group. This charge is sometimes called the Noether charge.Thus, for example, the electric charge is the generator of the U(1) symmetry of electromagnetism. The conserved current is the electric current.In the case of local, dynamical symmetries, associated with every charge is a gauge field; when quantized, the gauge field becomes a gauge boson. The charges of the theory "radiate" the gauge field. Thus, for example, the gauge field of electromagnetism is the electromagnetic field; and the gauge boson is the photon.Sometimes, the word "charge" is used as a synonym for "generator" in referring to the generator of the symmetry. More precisely, when the symmetry group is a Lie group, then the charges are understood to correspond to the root system of the Lie group; the discretenessof the root system accounting for the quantization of the charge.So what it's saying is, any system that has the ability, or symmetry, that separates some things from their nature state, and keep them there; is a charge. So there can be many different charges. But in electricity, only two,

Can ions have positive and negative charge?

An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.

What is it called when positive and negative charges transmit energy?

Because in an unbalanced system, the positive end a positive charge, and the negaticve end has a negative charge. Though current (which is reletive to the "positiveness" of an area) flows from positive to negative, electrons flow from negative to positive.


Where is the positive ad negative charge located in an atom?

In an atom, the positive charges are found in the nucleus. The nucleus contains protons and neutrons. The protons are positively charged while the neutrons are neutral.The negative charges can be found in the electrons which revolve around the nucleus.In a neutral atom, the number of positive charges (protons) is equal to the number of negative charges (electrons).
