The experience of hydrogen and metal atoms in luminescence
Recently, the experience of hydrogen and metal atoms in luminescence has been quite successful, as follows.
At the beginning, prepare various things, including hydrogen gas, salts of several metals, alcohol lamps, spectroscopes, etc. Burn the alcohol lamp, dip the platinum wire in the metal salt of the lamp and burn it. See the salt of sodium, the flame is golden and dazzling; the salt of potassium, the flame is light purple, and it needs to be viewed through cobalt glass to obtain clarity. Its color is different, because the atomic structure is different, and the light frequency emitted by the electron transition is different.
Also observe the luminescence of hydrogen. Put hydrogen in a special container, pass an electric current, and the hydrogen atom is excited to emit light. Looking at it through a spectroscope, several discrete bright lines are obtained, which are arranged in sequence. This is the spectrum of hydrogen atoms. Each line corresponds to a specific wavelength, which can be solved by Reibohr's theory. Electrons transition between different energy levels, absorb or emit light, and the light frequency is related to the energy level difference, resulting in spectral separation.
This test is of great significance in exploring the structure of atoms. Atomic spectra are like fingerprints, and elements can be identified. The spectra of various elements have their own characteristics, which help to distinguish the composition of matter in chemistry, astronomy and other fields. And the principle of atomic luminescence is the foundation of quantum theory. Although the Bohr model has limitations, it has opened the door to the exploration of the microscopic world, and post-quantum mechanics has flourished.
Looking at this test, we know that the road to scientific To see the essence from the phenomenon, you need to be sensitive to observation, have the courage to assume, and be willing to verify. This experience is like a key, opening the door to the microscopic atomic world, waiting for our generation to explore in depth and find more natural mysteries.
