It is believed that the number of electrons that would fit in the known [[universe]] is 10 followed by 130 zeros. == Listrik == When electrons move, free of the nuclei of atoms, and there is a net flow, this flow is called [[electricity]], or an [[electric current]]. This might be compared to a flock of sheep moving north together, while the shepherds do not. Electric charge can be directly measured with an [[electrometer]]. Electric current can be directly measured with a [[galvanometer]]. So-called "static electricity" is not a flow of electrons at all. More correctly called a "static charge", it refers to a body that has more or fewer electrons than are required to balance the positive charge of the nuclei. When there is an excess of electrons, the object is said to be "negatively charged". When there are fewer electrons than [[proton]]s, the object is said to be "positively charged". When the number of electrons and the number of protons are equal, the object is said to be electrically "neutral". == Sajarah == The electron had been posited by [[G. Johnstone Stoney]], as a unit of charge in electrochemistry, but Thompson realised that it was also a [[subatomic particle]]. The electron was [[discovery (observation)\|~~discover~~discovered]]ed by [[J.J. Thomson]] in [[1897]] at the [[Cavendish Laboratory]] at [[Cambridge University]], while studying "[[cathode rays]]." Influenced by the work of [[James Clerk Maxwell]], and the discovery of the [[X-ray]], he deduced that [[cathode ray tube\|cathode ~~ray~~rays]]s existed and were negatively charged "''particles''", which he called "''corpuscles''". == Tempo ogé == * [[Modél baku]] * [[Partikel subatomik]] Baris ka-69: * [[Sinar katoda]] == Tumbu kaluar == * [http://pdg.lbl.gov/ Particle Data Group] * Stoney, G.
