![]() Hydrogen molecules are first broken up into hydrogen atoms (hence the atomic hydrogen emission spectrum) and electrons are then promoted into higher energy levels. The high voltage in a discharge tube provides that energy. But if energy is supplied to the atom, the electron is excited into a higher energy level, or even removed from the atom altogether. The model has a special place in the history of physics because it introduced an early quantum theory, which brought about new developments in scientific thought and later culminated in. When unexcited, hydrogen's electron is in the first energy level-the level closest to the nucleus. Historically, Bohr’s model of the hydrogen atom is the very first model of atomic structure that correctly explained the radiation spectra of atomic hydrogen. Why does hydrogen emit light when excited by a high voltage and what is the significance of those whole numbers? Each line can be calculated from a combination of simple whole numbers. The lines in the hydrogen emission spectrum form regular patterns and can be represented by a (relatively) simple equation. The origin of the hydrogen emission spectrum The various combinations of numbers that can be substituted into this formula allow the calculation the wavelength of any of the lines in the hydrogen emission spectrum there is close agreement between the wavelengths generated by this formula and those observed in a real spectrum.Ī modified version of the Rydberg equation can be used to calculate the frequency of each of the lines: In other words, if \(n_1\) is, say, 2 then \(n_2\) can be any whole number between 3 and infinity. \(n_1\) and \(n_2\) are integers (whole numbers).
