Electric charge - Wikipedia, the free encyclopedia Electric charge is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interactions. Franklin imagined electricity as being a type of invisible fluid present in all matter; for example he believed that it was the glass in a Leyden jar that held the accumulated charge. Rather than one possible electric current there are many: a flow of electrons, a flow of electron "holes" which act like positive particles, or in electrolytic solutions, a flow of both negative and positive particles called ions moving in opposite directions. en.wikipedia.org /wiki/Electric_charge   (737 words)

Electric charge   (Site not responding. Last check: 2007-10-22) Electric charge is a fundamental property of some subatomic particles, which determines their electromagnetic interactions. Matter is actually composed of two kinds of electrically charged particles: particles called protons which carry a charge of positive electricity, and particles called electrons which carry a charge of negative electricity. Rather than one possible electric current there are many: a flow of negative particles, or a flow of positive particles, or a flow of both negative and positive particles in opposite directions. www.sciencedaily.com /encyclopedia/electric_charge   (698 words)

Atom - Printer-friendly - MSN Encarta Because atoms are normally electrically neutral, the atomic number also specifies how many electrons an atom will have. Because protons are electrically charged and neutrons are not, the reaction must involve other charged particles. The difference between the antineutrino in neutron-proton beta decay and the neutrino in proton-neutron beta decay is very subtle—so subtle that scientists have yet to prove that a difference actually exists. encarta.msn.com /text_761567432___5/Atom.html   (1734 words)

February 23 This flashlamp is electrically connected to a small but powerful capacitor to form a circuit so that if the flashlamp were to conduct current, it would allow current to flow from one plate of the capacitor to the other. Since the xenon atoms are electrically neutral, there are no free charges to carry current through the gas tube (the xenon gas acts as an insulator between the two plates). Now that the gas can conduct electricity, the circuit between the two plates of the capacitor is complete, and the 300 V potential drop between the plates will drive the electrons to flow through the gas. www.colorado.edu /physics/phys1020/phys1020_sp04/Ch12Case2.htm   (1745 words)

The Energetic Atom, Inertia, and Nonmaterial Interfaces   (Site not responding. Last check: 2007-10-22) While electric charge and magnetism are separate and distinct natural phenomena, the mutual relation between electricity and magnetism in the production of electromagnetic phenomena such as electromagnetic rotation (motors) and electromagnetic induction (generators) has long been known. The electrically charged quarks at the center of protons and neutrons are surrounded by inner and outer shells (clouds) of pions, much as the atomic nucleus per se is surrounded by shells (clouds) of electrons. Subnuclear quarks absorb and emit massless, electrically neutral (zero charge) gluons, the virtual exchange particles of the strong force, much as electrons absorb and emit massless, electrically neutral (zero charge) light quanta (photons). www.cox-internet.com /hermital/book/holoprt5-5.htm   (1553 words)

Ion Summary In a neutral atom, the charge of the electrons balances the charge of the protons, but when a cation is produced, the charges are in an imbalance. Ionic compounds are electrically neutral because the number of cations balances the number of anions and the charges cancel each other out. In the simple view of the Free electron model, a passing electron is therefore not attracted to a neutral atom and cannot bind to it. www.bookrags.com /Ion   (5386 words)

Neutral vs. Charged Objects The number of electrons which surround the nucleus will determine whether or not an atom is electrically charged or electrically neutral. In the previous section of Lesson 1, an atom was described as being a small and dense core of positively-charged protons and neutral neutrons surrounded by shells of negatively-charged electrons. In conclusion, an electrically neutral object is an object which has a balance of protons and electrons. www.glenbrook.k12.il.us /gbssci/phys/Class/estatics/u8l1b.html   (1319 words)

The galvanic cell and the p-n junction P-type Si is electrically neutral in its bulk regions, with equal concentrations of ionized acceptors and holes. The lowering of the hill means that the electric field is smaller, and the diffusion current of electrons and holes now prevails over the drift current: a significant number of electrons have enough kinetic energy to climb the hill (the electron PE is higher on p side, even though the electric potential is lower there). This is a standoff between the electric field repelling ions and a diffusion dendency of the ions to move toward the electrode. www.rose-hulman.edu /~moloney/BoisePNjunctionOperation.html   (1563 words)

Plasmas As stated in the definition, plasma is a gaseous type of state where the matter making the plasma consists of electrically neutral and charged particles. Overall, plasma is electrically neutral having as many positive ions as free electrons distributed through it. We apply an electric voltage to the metal electrode in the center of the plasma globe. www.4physics.com /phy_demo/plasma1.htm   (853 words)

The Origin of Matter and Information This is all that remains of the antileptoquark Lq, which being electrically neutral, and with its color charge vanished due to the compression of its quarks by the X, will simply convert its neutralized mass-energy to particle-antiparticle pairs and self-annihilate, once its number charge has been canceled by the leptoquark neutrino "vlq". This electrical neutrality is the reason why this reaction requires a composite particle whose constituent quarks can sum to zero electric charge (as in the neutron). In most reactions, the leptoquarks will be electrically charged and simply annihilate each other; of those in which the partners are neutral, most will annihilate each other or decay simultaneously despite their electrical neutrality. www.people.cornell.edu /pages/jag8/origin.html   (3124 words)

Matter and Its Changes In an electrically neutral atom, the number of electrons equals the positive charge on the nucleus. This means that in an electrically neutral atom (one with an equal number of protons and electrons), the postive charge of the protons, combined with the negative charge of the electrons, would result in no charge because they would cancel each other out. Atoms are electrically neutral as they contain an equal number of positive and negative charges. library.thinkquest.org /10429/high/matter/matter.htm?tqskip=1   (1470 words)

Coalition for Plasma Science - What is a plasma? Those atoms and the resulting electrically charged gas are said to be "ionized." When enough atoms are ionized to significantly affect the electrical characteristics of the gas, it is a plasma. In many cases interactions between the charged particles and the neutral particles are important in determining the behavior and usefulness of the plasma. One version [2] of the story has it that the similarity was in carrying particles, while another account [3] speculated that it was in the Greek origin of the term, meaning "to mold," since the glowing discharge usually molded itself to the shape of its container. www.plasmacoalition.org /what.htm   (650 words)

What's a Neutrino? Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons. Hence, the "electron neutrino" is associated with the electron, and two other neutrinos are associated with heavier versions of the electron called the muon and the tau (elementary particles are frequently labelled with Greek letters, to confuse the layman). Pauli suggested that this missing energy might be carried off, unseen, by a neutral particle which was escaping detection. www.ps.uci.edu /~superk/neutrino.html   (946 words)

Spaceflight Now | Breaking News | Solar wind find may help space weather forecasting This is a picture of the electrically neutral atoms in the solar wind as detected by NASA's IMAGE spacecraft on June 8, 2000. Scientists thought that within this gale of electrified atoms, a few might manage to obtain a complete complement of electrons and thus be rendered electrically neutral (the number of surrounding electrons, which are negatively charged, balances the number of positively charged protons at the center of the atom). According to the theory, the CME clouds should carry a higher population of neutral atoms than the solar wind because they come from near the solar surface, where it is much cooler than the solar atmosphere, which is the source of the solar wind. spaceflightnow.com /news/n0105/28solarwind   (1115 words)
