First he tried the formula:

Niels Bohr derived this expression theoretically in 1913. E 0 1 By setting n 1 to 1 and allowing n 2 to take on values of 2, 3, 4 â¦ â the lines take on a series of values known as the Lyman series. ′ Later, Niels Bohrâs concept of quantized âjumpsâ by electrons between orbits was shown to be consistent with the Rydberg equation. It can also be used to find the frequency of light necessary to excite an electron to a certain energy level. Rydberg's 1888 classical expression for the form of the spectral series was not accompanied by a physical explanation. For other spectral transitions in multi-electron atoms, the Rydberg formula generally provides incorrect results, since the magnitude of the screening of inner electrons for outer-electron transitions is variable and not possible to compensate for in the simple manner above. n 2 . According to the Bohr model, energy released between n=3 and n=2 is less than n=2 to n=1, so option n=2 -> n=1 is your answer. Rydberg Constant An introduction to the Bohr Model of the Atom. R. given by: 4. Rydberg rewrote this in terms of wavenumbers as n = n o − 4n o /m ². It turns out that there are families of spectra following Rydberg's pattern, notably in the alkali metals, sodium, potassium, etc., but not with the precision the hydrogen atom lines fit the Balmer formula, and low values of \(n_2\) predicted wavelengths that deviate considerably. In 1884, Johannes Balmer, a Swiss high school teacher, first determined that the prominent emission lines of hydrogen gas had wavelengths which followed the simple equation This theorem says that the total energy of the system is equal to half of its potential energy and also equal to the negative of its kinetic energy. The Rydberg equation (sometimes called the Balmer equation) is an analytical equation for determining the wavelength of a photon emitted or absorbed when an electron changes energy levels in a hydrogen atom.. Other spectral series may also be determined: For most problems, you'll deal with hydrogen so you can use the formula: where RH is Rydberg's constant, since the Z of hydrogen is 1. m = Balmer's Constant has a value of 3.29 * 10 15 s-1 and is denoted with a capital C (not to be confused with c, the speed of light in a vacuum).
