"Unfortunately, the analogy breaks down, and we have come to realize that it is misleading to conjure up an image of the electron as a small spinning object. Instead we have learned simply to accept the observed fact that the electron is deflected by magnetic fields. If one insists on the...
What is the magnitude of the electric force between a proton and an electron when they are at a distance of 2.63 Angstrom from each other? The electron in a Hydrogen atom is 45 picometers from the proton. What is the strength of the ...
electrons, so the atomic number of an element also gives the number of electrons. Helium has 2 protons, so its atomic number is 2. Atoms are neutrally charged, so what links atomic number and the number of electrons? electron proton ...
一道英文的物理题When a proton captures an electron,a photon with anenergy of 13.6 eV is emitted.What is the frequency of thisphoton?Does it lie in,above,or below the visible range?答案 当一个质子捕获一个电子时,会发射出一个具有13.6电子伏能量的光子,请问这个光子的频率是多少?它是否在可见光...
By choosing electron events with field-aligned beam-like anisotropy (that we know are magnetically well-connected to the injection site), we believe it likely that the proton anisotropies are also beam-like. Hence these proton events are also likely to have nearly scatter-free propagation, so ...

835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that...
Located within the nucleus of the atom, a proton has a relatively larger mass than that of an electron but slightly smaller than that of a neutron. A proton will always have at least one positive charge. The proton is responsible for the atom's atomic number. The positive proton charge ba...
An electron has a momentum with magnitude five times the magnitude of its classical momentum. What is the speed of the electron? Special Theory of Relativity: For particles moving at great speed, where theirs speeds are a substantial fraction of ...
Electron Loss or gain leads to ionization. Gaining an electron forms a negatively charged ion. 5 Proton Defines the chemical element. The atomic number, equal to the number of protons, identifies the element. 2 Electron The electron is a subatomic particle, symbol e− or β−, whose elect...
