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...
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...
