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 ...

cloud of negatively-charged electrons. By definition, atoms are neutral entities because the positive charge of the nucleus is cancelled by the negative charge of the electron cloud. However, the gain or loss of an electron can lead to the formation of an ion, also known as a charged atom....
Together, protons and electrons form an atom'snucleus. A proton has a positive charge that counters the electron's negative charge. When an atom has the same number of protons and electrons, it is in a neutral state. Electrons are unique from the other particles in multiple ways. They exis...
An electron is a very small piece of matter with a negative electrical charge ,found in all atoms.电子是构成原子的基本粒子之一,质量极小,带单位负电荷,不同的原子拥有的电子数目不同,例如,每一个碳原子中含有6个电子,每一个氧原子中含有8个电子。能量高的离核较远,能量低的离核较近。通常将电子在离...
