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...
The antiproton was discovered in 1955. Unlike a proton (which has a charge of +1), an antiproton has a charge of -1. It is different from an electron because although an electron also has a charge of -1, electrons have a tiny relative mass whereas antiprotons have a relative mass of...

"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...

Electrons have no measurable mass. No quanta. They are not physically definable as a particle. An electron, in practical electrical engineering, is a field perturbation. Where is the proof that this perturbation has a mass and can be observed as a particle? There is none. J.J. Thompson den...

Which subatomic particle was discovered first? An electron and a proton are 2.0 nm apart. What is the magnitude of the electrostatic force of attraction between the particles? What hold quarks together? Why are atoms neutral despite having charged subatomic particles? Which particles make up the ...
Atoms were once thought to be the smallest building blocks of the universe, until it was discovered that even they were constructed of building blocks of their own. Those building blocks are protons, electrons and neutrons, and with the advancement of science it has been discovered that each of...
But let's suppose you could turn atoms into other atoms very simply. How would you make the first few chemical elements? You'd start with the simplest atom of all, hydrogen (symbol H), which has one proton and one electron, but no neutrons. If you add another proton, another electron...
