Electric charge Electric charge, also referred to simply as charge, is a basic property of some fundamental particles of matter. There are two types of charge: positive and negative. For example, an electron has a negative charge, and a positron (an anti-particle of electron) has a positive...
The charge of a single electron is referred to as the unit electrical charge. It carries a negative charge that is equal to but opposite the positive charge on a proton or hole. However, the amount of electrical charge is usually not measured on a single electron because that amount is so...
An electron is a subatomic particle with a negative elementary electric charge. The electrons are generated from a tungsten or tantalum filament and directed by a high voltage source inside a vacuum chamber. The energetic electrons pass through a metallic foil that is thin enough to allow electron...

LAST January I proposed a theory of electric charge which led to a definite prediction of the numerical value of the constant hc/2πe. Since then I have been trying to obtain fuller insight into the more obscure parts of the theory-places where it was necessary to trust to a sense of ...

aBecause an electron will only occupy a certain electron shell (shells are well known) the voltage applied to the capacitor affects the electrical forces inherent in the covalent bond. As a result of the charge applied by the plates, the applied force becomes greater than the force of the ...
(a second mechanism of charge transfer is byoxidationof the electrode metal: the metal leaves the surface as charged cations and enters the solution). Without electron transfer, there is no chemical electrode reaction, no DC electrode current, and no faradaic current. In the solution at the...
A suck-out pulse of –90 V was employed to extract positive ions and a similar pulse of +90 V was employed to extract negative ions; the detection system responded to both positive and negative ions, the former probably causing secondary electron emission from the deflection electrode. Today,...
