Energy states and transitions in hydrogen atoms
As the simplest atomic structure, the energy states and transitions of hydrogen atoms contain many mysteries of quantum mechanics.
The energy states of hydrogen atoms are not continuous, but quantized. According to quantum theory, electrons in hydrogen atoms can only be in specific, discrete energy states, which are determined by the principal quantum number\ (n\). When\ (n = 1\), the electron is in the ground state, which is the lowest energy state of the hydrogen atom. As the value of\ (n\) increases, the energy of the energy state gradually increases, and the orbit of the electron is farther and farther from the nucleus. For example, when\ (n = 2\),\ (n = 3\) and other states are all excited states. The transition between the
energy states is another key phenomenon. When the outside world provides energy to the hydrogen atom, such as photon irradiation, if the photon energy is exactly equal to the energy difference between the two energy states, the electron will absorb the photon and transition from the lower energy state to the higher energy state. This process is called the excitation transition. On the contrary, the electron in the excited state is not stable and will spontaneously transition to the lower energy state, while releasing energy in the form of photons, which is called the emission transition. The energy of the emitted photon is precisely equal to the energy difference between the two energy states. According to the formula\ (E = h\ nu\) (where\ (E\) is the energy difference,\ (h\) is the Planck constant, and\ (\ nu\) is the photon frequency), it is possible to calculate the frequency of the emitted or absorbed photon, so as to determine its position in the spectrum.
This energy state and transition phenomenon is not only the cornerstone of understanding the unique laws of the hydrogen atomic spectrum, but also a key entry point for in-depth exploration of the atomic structure, molecular structure, and various light-matter interaction processes. By precisely studying the energy state and transition of the hydrogen atom, scientists can gain insight into the working mechanism of the microscopic world, laying a solid foundation for the development of quantum physics.
