在学习氢原子能级跃迁时,我们应熟记一些重要的二级结论,本部分的两个重要结论。分别是:1.一群氢原子处于量子数为n的激发态时,可能辐射的光谱线条数为N=(n(n-1))/2。2.根据氢原子的能级分布规律可知:量子数越大,相邻能级间的能量差越小。例1一群氢原子处在n=3的激发态,这些氢原子能发出几条谱线?计算这几条谱线中波长最长 When studying hydrogen atom level transition, we should remember some important secondary conclusions and two important conclusions in this section. Respectively: 1. When a group of hydrogen atoms is in the excited state with quantum number n, the number of spectral lines that may be radiated is N = (n (n-1)) / 2.2. According to the energy level distribution law of hydrogen atoms, The larger the quantum number, the smaller the energy difference between adjacent energy levels. Example 1 A group of hydrogen atoms in the excited state of n = 3, these hydrogen atoms can emit several lines? Calculation of these lines in the longest wavelength
