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...
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...

Atom (原子)被认为是the smallest part of an element that has the properties of that element,它自身又由proton (质子), neutron (中子)和electron (电子)组成。虽然electron的质量仅为proton or neutron的1/1836,但它在许多方面(e.g. ionisation energy, chemical bond, etc. )发挥重要作用!
